Can Vortec heads handle a crane powermax 272, duration--272/284 gross lift--454/480.
if i have to change valve springs what springs do i need. Just talked to jegs and they said the vortec heads with this cam would be fine. due to my valve relief (this looks like 2 mustaches 1/4 wide 1/8 deep grooves on each side of the piston) any other help on this would be appreciated.
