Re: camshaft options
the cast numbers for the hp 305 heads are 14014416 they got a 58cc combustion chamber and 1.84 int /1.5 ext valves. (if i remember correctly) the hp cam you spoke of would work good with these heads. if they just plan old 305 heads stick with the rv cam. if you looking for performance id find a 350 lots of bang for the buck. hope this helps, just my .02 cents worth
