Right choice for valvesprings Hi everyone , im new to this forum.
I bought a new camshaft for my 97 corvette , the comp cams 54-459-11.
specs:
hyd. Roller; 2000-7000rpm; Adv. Dur. 281 Int./289 Exh.; Valve Lift .617 Int./.624 Exh.; Lobe Angle 113 deg.
Which would be a good choice for valvesprings to.match the new cam ?
thanks everyone.

I would also plan on larger OD pushrods for the springs that will be required for control and the RPM of that cam.
Couple of quick questions. What have you done to the exhaust side, headers? How about intake, are you still running the LS1 intake? That cam is going to need a lot of supporting components to function properly.

Second, the max lift rating of springs are usually spec’d with an excessive amount of coilbind built in. A spring kit with .630” max lift rating would most likely be fine with .624” valve lift, and in my experience, could even use a little shim to bring the coilbind clearance down
