Head gasket recommendation
Getting ready to put heads on my new build. Compression will be approximately 12:1,ported W2, 410 X block, .650 lift roller, Race motor only.
My local machine shop has done a nice job with the machining of the block, but the surface finish is not optimal for an Mls Cometic. I see that Felpro and Mr. Gasket now make Mls gaskets that "supposedly are designed to seal rougher surface finishes while still having the benefits of the Mls. I have never had any trouble with the Felpro 1008 blue in past builds, but those builds did not use this much compression. I have also seen a YouTube video by Cometic that stated although they do not recommend it, if you have to spray your gaskets, to use hylomar.
My local machine shop says not to fall into all the hype about surface finish, that they have used Mls all the time without issue.
Will the Felpro 1008 work reliably at 12:1 or is there another option. Will be using studs by the way.
Any input appreciated
