Seems to me like it would actually be better than as machined. His blast is satin smooth. Here is a cover he did off the Buffalo I had as an example of the finish.

Gasket Surfaces
I know I'm asking a lot of questions lately, but I'd like some opinions on this. I'll be taking the cylinders and head to be blasted to remove the black paint and freshen things up. Concerning the head, I'd like to have the carbon blasted off the inside. A) would I need to polish the domes back shiny? B) Would the as blasted surface be an acceptable head gasket finish?

I was born with nothing and still have most of it left.

Re: Gasket Surfaces
The blasted surface would be fine for the gasket (IMHO) and I'd do a little bit of polishing on the cylinder head domes. But that's free advice and worth every penny !

Re: Gasket Surfaces
I dont know if its true but i have practiced a polished head and exhaust port made it a bit more difficult for carbon to stick to and build up .
the older i get the faster i was

Re: Gasket Surfaces
+1 to both replies.
In theory, polishing the combustion chamber and exhaust port help to slow down carbon build up but OEMs didn't bother, so it's optional.
For gasket surface, make sure they are dead flat first and then have them blasted should work just fine.
