the head studs were no problem to get out with a propane torch.

i am thinking about the piston rings, i did a leak down before disamble and it was only 2% leak is it still nesasery to change them do guys think. i meen the engine was runing fine i just wanted to change cams and now rebuild the heads.

how about the head seal, how mutch boost could i have before there are leak problems betwen cylinder and heads?

i have still have not made up my mind about the head studs
i thinking of ARP head studs, i have them i all my other engine builds and they are never a problem but the porsche engine seems sensitive about those studs.
anyone have had problems with ARP head studs?
