Does anyone have any info on the specs for each of these...like valve sizes and cubstion chamber size and what ever else is involved. I have a shop that is gonna do the swap for me and we are trying to figure out which heads to go with. No matter what we are gonna do head work but we are trying to see where is the best place to start.
