Good info Randy. I really like that Coronet alot and was looking forward to seeing more of it.

Call Cometic's, They will get you the correct gasket for your application, they were great to work with and got me the correct gasket for my KB alum hemi with the steam holes in the proper location.

They have my head gasket on file, always great to work with. But the HEMI is going top fuel hoops.

The first blown pump gas KB street Hemi block I assembled and dyno tested years ago leak water into the motor due to the sleeves being a tad bit too high , .005/.006 instead of .003 to .004 at room temps. It was a 4.375 bore with a Mopar brand 8 bolt 4.150 stroker crank.
Long story short I ended up working with SCE gaskets to get a custom set of their ICS Titan head soft copper head gaskets made to cure all the gasket sealing issues I had with that project
I'm getting ready to start making a 4.500 bore new KB street wedge 572 C.I. B1 race motor for myself and I bought a set of the SCE Titan head gasket with the Teflon sealant rings around all the water passages ,
That type of gasket worked really well for me on the last KB aluminum block I built: up:
I've also use them on other cast iron blocks high compression builds and roots blower motor builds with really good success IHTHs

My question is how much torque on the inside bolts -M1 heads? How much on the others also?

That is one super super nicest 9.85 street cars you will ever see...Rob has like OCD for these things....And he goes all out when trying things. I think he has tried ever carb/intake combo available on that car I think except an SV1 which I tried on mine.... If you ever get to talk with him, he has a lot of knowledge locked away up there of what works and what doesn't....We call him Mr. Sixpack.....He really has a thing for those.

Yeah from the few pictures he's posted here, that car has got the attitude and the performance.

I can tell by the pics it's real close to my target with the GTX but in many ways it seems a couple notches above where it'll end up.
