The heads under consideration are the Enginequest 220cc with 50cc chambers. I have a pair of 1.75 dia. sprint car headers that I will tryout at the track also.
The 220 heads flow better than what I have now plus the compression gets raised a bit. The local speed shop thinks the gain will be more like 40-50 horse... The current headers are for looks. I know they are far from optimum.
