I would start by adjusting the valves properly and see what you have after that, a good tune-up, and cleaning your carb. Assuming hydraulic lifters, you loosen them up, tighten to take the slop out of the pushrod, and tighten 1/2 turn. Here is a link to the full procedure and proper sequence http://www.centuryperformance.com/valve-adjustment-procedure.html | | |
