preping the block

[IJ.]

I'd use it and will do so on any motor I build from now on!

Very impressed with it the only con to using it is it's sticky shit so EVERYTHING must be spotlessly clean and ready to go before you lay is down on the deck! (You'll find the neighbour kids stuck in it if you're not careful! )

so far everyone is only talking about the cometic MHG? is that the only one out there everyone trust? i know theres also HKS and Titan out there. personally i dont see spending the money on the HKS either. but i assume everyone out there is going with the ARP head studs right? something i wasnt sure on when those are installed is does anyone put locktite on those before they go into the block? whenever i worked on small blocks we always put locktite on the side going in the block, then anti-sieze on the nut side. also i heard the thread takes a 14mm tap? does it have a special pitch on it? or is just a normal close thread design? like is the tap special order from toyota or something. because that is something you deff want to do while your in there too. run a tap down the threads to clean it up.

12x1.25mm tap

The Cometics can get away with a less smooth surface finish than the HKS so seem to be the MHG of choice.

I just install the ARP's as per the included instructions.

Update to this thread/topic!
Personally I won't use the PermaTex Brake Quiet on any gasket that uses a Fluorine/Viton rubber coating as there are ingredients in the BQ that don't play well with the Rubber coating.

i mean that sounds great and all but im more then half of the supra cumminity has probley done it in the car

And half the community has blown their headgaskets more than once.
