Shucks, then use those!! They did all that work and left the press-in studs?? If so, IMO it's worth it to have them properly installed. 58cc is correct for a '71 302. Compression was around 9:1 for '71. Use a .039 head gasket over a .047 (like the Mr. Gasket pair). If the machine shop even milled 'em .010 to clean-up, that'll help also. Should run good w/ the small Thumpr cam!

Thank you!! I think I now have a plan!

Don't you just love it when a plan comes together.
