Ok, I have read alot about these 305 heads (601) castings and I have heard great things and bad things. I got these head completely rebuilt and with 2.02 and 1.60 valves. No port work has been done. I plan on running these with stock bottom end, lunati bracket master II, edelbrock rpm performer Intake and carb 600 cfm, and long tube headers. I was curious what type of hp I can expect? I am also looking at dish pistons. What compression will I run with this setup. thanks for answering a rookies questions.
