We put those heads on a GM Goodwrench Target Master engine.
Put a Comp Cams Xtreme energy XE274H:
RPM Range: 1800-6000
Performer RPM intake, 650 dbl. pumper, 373 gears in an 86 Chevy C-10 pickup. Only thing I would do different is more converter. It has a 1800-2000 in it and I would go to a 2400-2600 for more ooomph....
***Edited*** Oops, should have pointed out this motor is a .030 over 350 not a 327.
