I'd run a solid roller with a McFarland Torque Link intake or Single Plane Dart with a Demon 825 RS- minimum if not a 975RS just change the carb sleeves if need be with tuned headers. H-rollers suck for competition. And give Ken from Oregon Cam grinding Service all his cams are USA. And the turn around is 72 hours from ordering via UPS. Do not get a Comp Cam. The last 5 cams from flat tap pet to roller HAVE FAILED due to MANUFACTURING DEFECTS. How embarrassing for quality.
Here is Ken's number. 1(360)256-7985
Run a cast iron gear and a full base circle- if you got the clearance. If you can afford it a 4/7-2/3 swap will help.
