Hey guys, I need some help figuring out what roller rockers to use. I am building a 331.I am using Gt40P heads, Trick flow Track heat intake, and a comp cams xtreme energy cam.

Cam Specs:
Basic Operating RPM Range:2,200-6,200
Intake Duration at 050 inch Lift:224
Exhaust Duration at 050 inch Lift:230
Duration at 050 inch Lift:224 int./230 exh.
Advertised Intake Duration:276
Advertised Exhaust Duration:282
Advertised Duration:276 int./282 exh.
Intake Valve Lift with Factory Rocker Arm Ratio:0.544 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio:0.544 in.
Valve Lift with Factory Rocker Arm Ratio:0.544 int./0.544 exh.
Lobe Separation (degrees):112

What ratio would be best for me? And should i stick with the pedestal mount rockers or convert to stud mount?
Thanks for the help!

Awesome thanks. Do you have a link to the rockers you are talking about? The only comp cams rockers I can find are aluminum.
