PSI Valve Springs & mopar performance hyd cam

Where can I get a set of mopar yellow terra rockers?


I would use comp #995 valve springs, shim to 1.68 and get more seat psi... like 130'ish
Ideally 130-140lbs seat and 315-340lbs open with that purple cam

Thats yella terra....And you can get them from here.

These are my heads, I don’t know if there been machined or not.
They came with these springs & heaps of shims...There are only 14 springs 2 were lost when the guy pulled them apart a few years ago...That’s why I’m looking for another set.
