I am wondering if I am going to get into trouble running the following combination on my Gen VI 502 with stock valve reliefs: I think Ill be ok but just wanted to double check.

AFR 325cc Magnum heads (119cc chambers) with crane cams powermax hydraulic roller cam:

Grind Number: HR-226/345-2S-12 IG
Operating Range: 2500-6000 RPM
Duration Advertised: 288° Intake / 298° Exhaust
Duration @ .050'' Lift: 226° Intake / 236° Exhaust
Valve Lift w/1.7 Rockers: .587'' Intake / .610'' Exhaust
Lobe Separation Angle: 112°
Max Lift Angle: 107° ATDC Intake / 117° BTDC Exhaust
Open/Close @.050'' Cam Lift: Intake - 6° BTDC (opens) / 40° ABDC (closes)
Exhaust - 55° BBDC (opens) / 1° ATDC (closes)


Also, crane cams reccomends 9.5-11 compression ratio. I think the best i can do is closer to 9. Is this an issue?

Any good 502 combinations out there? Looking for 600+ hp
