Reuse my MHG's an average of 4 times each after careful inspection before I retire them to the bin

HA, ok. Does it matter which on you have? Mine is the cheap HKS gasket. The only thing to note is that the coating is mostly peeled off. Should I use a spray on coating before installing it? I have hear of using brake quiet.
Do a search for MHG reuse I started a big thread on this subject a few years back.suprahilux;1574205 said:

Well, thanks for joining us. I hope it doesn't disappoint.
Thanks IJ for your information.

There is little feedback on the brake quiet spray. I wonder how that works, but I guess if everyone is using the copper gasket spray with success then I should just stick to that.
Here are some more updates. I haven't been able to do very much the past couple of weeks. I quit my job and now am doing any work I can get. I may not get to work on this every weekend, but I may get some down time during the week.
I reassembled the SC after striping and painting it. I have the harness 95% complete and the DIYPNP megasquirt computer is assembled and tuned with what I think will work as a good base map. I decided to have the MS fire the coils directly instead of using an ignition module. The block is stripped and ready to go to the machine shop. I am waiting on the arp rod bolts.
I assembled the SC on the engine so that I could size up the harness. Here are some pics of that:

Suscribed! This is American innovation lol
Very neat project.
What was wrong with the job you had? In this economy ppl generally try to keep jobs. Are you gonna be your own boss or just wing it awhile?

HA! Yeah, everyone asks why and says in this economy... It was appliance repair. I was the top technician for several years and carried them through many other employees coming and going who cost them a lot of money. I deserved to get paid much more and they wouldn't give it to me. I know exactly how much money I was making for them. I finally decided to leave when it got to me that an unemployed friend made 5000 more last year than me. He is a body man. He picks and chooses his jobs. So I took the plunge. So far, I am making more per week doing 'side jobs' than at that place. Right now I have stuff lined up this week and prospective work lined up next week. Collision repair and engine/drivetrain. I have even considered throwing a couple of these SC kits together and selling them. I'm just not sure if anyone would be interested enough to pay the price. For the next month or two, I guess you could say I'll just have to wing it. But soon, I should have a very steady income working for myself. I didn't go into this without a plan.
So, yeah. Keeping a dead-end, underpaid job because of the economy just won't cut it. Besides, The Great State of Texas has been affected very slightly by the poor national economy.

So your helping the 'body' man's customers on the side turning wrenches i take? Thats works, way to think outside the box.
The SC setup intrigues me, guess i'll just have to wait and see how it performs.
Keep on keepin on buddy

Yeah, I'll do engine work and help him with the body work. We both do it all. I just have more experience building engines and he has more with paint and body. I have done body work with his close supervision, but I don't like doing it. It sucks. We have a collision job this week.
I am also doing the body work on my truck. I haven't posted updated pics of that because I don't like the look of unfinished body work. Probably when it is all one color. So hang on for that.

Sweet deals man!
I know what you mean about body work. I never done it myself before til i shaved the door handles myself the right way. Just needs finish coat paint (never operated a gun yet), but Goshdang did the body work look bad at first lol
The Stinger your wiring in for this project, what resolution MAP sensor are you using, just the GM 3 bar? I'm starting to learn about stand alone systems

I am not using a stinger. It is a megasquirt. And it has a 2.5bar map installed. So, 22psi max. If I go beyond that, I will have to swap the turbo anyways.
Have you messed with piggyback setups yet? That is were I started. I suggest that everyone should start with those. Much easier to setup and tune. I used a safc neo for a while on a slightly modded 7m. I learned a lot, especially the limits of the electronics when I got boost hungry and turned it up.

The last couple years i've had an okay experience with the maft-pro.
Its pretty idiot proof with that afr tracking auto fixing feature
I didn't go into timing monitor or do the timing set mods for it though.
Its time to graduate to something that will foot the power i'm building to, so i'm looking into reasonable standalones and trying to figure out how much of the stock systems going that route will render useless.
The megasquirt has evolved rapidly and has an ever growing user base with tons of options.
I'm not sure thats the route i should take until i learn more about it.

Oh, still here. I see the engine every day now, but never get to work on it. Today I decided it was time to drop the block off at the machine shop. It's there for a little work including punch out 20 over. It was there not long ago for the last build so they don't have to do much. I am debating if I should have them do a 5-angle on the head. I rebuilt the head last time, porting and polishing and etc. Not sure if I want to spend the extra to have them do a valve job on a perfectly good head. I will be running BC 264 cams. Would it be worth it? They said they could do it for about 150 on an unassembled head.
3 angle is fine. all a 5 angle is is the 3 angle radius cuts, plus 2 more at the intermediate "humps" to smooth them out more.
Example:
Picture a street corner from top view.
Normally when driving, a person cuts the wheel an amount and makes for smooth cornering, a smooth radius, as if the machinist had the variety of bits and time to cut the seat surfaces that smooth.
Using the street corner example, 3 angle is the taking same corner, but jerking the wheel and straightening and jerking the wheel and straightening and jerking the wheel and finally straightening to your finished direction. Now you have 2 lumps of roughness.
5 angle remove the 2 lumps of roughness, equal to not jerking the wheel so far each time you have to correct for smoother cornering.
3 angle interlocks the valve and seat just fine, plus with boost, the "rough" corners shouldn't be a real restriction.
Shops vacuum test individual combustion chambers to make sure their valve job is good before giving the head back to you.

Thanks, but I know what it is. I wasn't sure if I would benefit from a valve job enough to spend that money. I read on a 'honda' forum (sorry) that the 5 angle gives you less contact on the valves that would not be ideal for street purposes. Less heat transfer. A 3 angle is standard on some OEM engines including most hondas and corvettes. I think though that I would get the 3 angle if I have it done. My question is would I gain a noticeable amount of flow on a 7m head with a 3 angle on stock valves or is it a waste?
The valves were lapped about a year ago and they seal just fine. But it has been ported and polished and I will run bigger cams. It seems like the stock valves would be a huge restriction, but I am not sure if I would see gains at the power levels I plan to run.
