What will my compression be (estimated) I am going to be buying heads and was thinking of buying patriot 5.3l but i won't to know how much they will raise my compression over my stock 5.7 ls1 heads. I will be using gm head gaskets. I am looking for a good estimate.
also anyone know if the 7.4" pushrods would be the right set up to use with these heads an a thunder racing cheater cam. I really hope so i just bought them. Will these heads cause me to lose piston to valve clearance?
Thanks Dan
