Hey guy/gals, I am building a slant with an eaton m90 bolwer. I plan to run approx 10psi with stock compression and .40 overbore. Just wondering what head gasket will get the job done.
Thanks

Stock compression and ten lbs, you should be able to use a stock type gasket, as long as you stay out of detonation. If you feel you need something more, copper gaskets are available, from Hussey Copper.
Which Englewood are you from, near Jacksonville, or down by Bradenton?

If you decide you want a heaver fire ring than a standard Fel-Pro. I stock the Permaseal Aussie head gaskets.

I agree with charlie,NOS steel head gasket,10 LBS of boost and NO problem! But you must be sure the head and block surface are true.

I have been running an aussie permaseal head gasket in my procharged slant at 12lbs boost with no problems what so ever. The only thing, like suggested in one of the other posts is stay out of detonation. Best to invest in a wideband O2 for tuning on a boosted application as well.
