I was wondering if the MegaTork Valve Springs #MT351 Will suite a camshaft with intake .515 and exhaust .541. I cant seem to find a MegaTork Webpage listing there products, so if somebody could shed some light that would be very much appreciated.

Roller cams usually have to have high spring loads..Check but from memory 130 installed and 300 or so Lb at full lift...
Check with Cam supplier...

the compcams is only hydraulic, but im not sure whether ill get coil bind with the DEH275 cams lift with these springs?
