Cometic Head Gaskets with no machine work?

[tte]

Just get both the head and block machined. This will make both surfaces flat and true. You take shortcuts, then expect to spend more money and time in the future pulling it all apart for another BHG.

Take the good advice offered by those who have been there. They are here to help you out and ensure that you do not take the route some of them took and repeat their mistakes. This will save you money and time in the long run.

Cheers,
Roy

...For the record, the key to having a long healthy headgasket life is the tune. Avoiding detonation. IIRC MK3Brent is still on the EOM headgasket with 400+ RWHP... XMan helped tune a car with 500+ RWHP on the OEM. If I had another 7M, and I were on a strict budget, I'd go OEM, and keep it tuned properly.

well said.

the internet myth that the stock HG is only good to XXX rwhp is retarded.

This thread makes me happy bc i am about to buy a car w/o BHG but it has been sitting for 5 years and i was alll worried about HG troubles and milling the block etc...

thanks for the info guys i apprciate it. i think im just gonna stick with the stock hg and try and make it work for awhile and just save for my build. i kno the head and block should b machined just thought there would be a glimmer of hope that maybe i could get away with it but i guess not and im not gonna take a chance.
sorry if i sound kinda pissed just a bit on the frustrated side. ill keep the car up until the summer and depending on how well the summer goes we'll see what happens with my supra hopefully all turns out well. hopefully if i take care of the motor and keep it tuned well it'll last till im ready. maybe i do some body or suspension work this summer on it. thanks again

just check the tq on the head bolts, retq to 72 and tune it right....there's nothing to be pissed about...

Don't run it/start it!

Tow it home pull the head and feed it a new HG, point in case a friend of a friend had a 18000 mile Mk3 that had been sitting for many years my friend bought it then proceeded to drive it home.

It lasted 8KM's (about 5 miles) before it popped the stock gasket and I got the call to tow it home for him.

good luck!

nothing like skipping steps....i look fwd to the "why did my MHG blow" thread....

do it right or do it twice....

By the way, not familiar with a Supra doesn't mean much. The machinist is following book specs on everything. If they aren't, don't give them your business.

o yea and jdub, i read the thread you have linked here and i see that he had a problem cuz he didn't prep his head for a HKS type head gasket.

Just trying to make a point man...I see quite a few others chimed in, so I'll keep my mouth shut.

Besides, what do I know

Don't listen to him. He's quite mad you know. Uses thin oil in his engine
