Small block 273 920 head porting services.
Much appreciated. I have done some heads and can do these if I can't find someone. But I have other projects going on and my work at best would pale in comparison to some of the stuff I have seen guys on this site do. I'll need 11/32 guides, hardened seats, preferably nitrate treated plus the Porting. Also I assume the porters here will know which valves to use. I'm thinking chevy 1.84 1.6"
