cams like:
Crane 227
Linginfelter 211
GM 845
all work with stock heads. Low end TQ for a street car is where you feel the power with these cams. They are good up to 5500-5700 RPM
with that said valve springs (26918) retainers, and 1:6 RR are what you would want to also add. Your stock 7.200" PR will "work" but most upgrade to a .080 thick wall hardened PR to prevent flex at high RPM's and also because most go with NSA RR & guide plates. You can run SA and stock PR if you want. Just don't go reving 6300 rpm all the time.
it is HIGHLY recommended to replace valve stem seals while doing springs. FelPro Viton are good ones
A FelPro timing cover gasket kit and intake gasket kit. You don't need to pull the heads so head gaskets are not needed. 2 gal of coolant.
you may discover your timing chain needs replaceing. A stock replacement from somewhere like NAPA is fine.
point is there are more parts than just a "cam" involved...includeing a new tune for it to run/perform right. Plan your budget accordingly
also confirm whatever cam you pick, the dowel pin is EXACTLY the same length as stock.
