What about camming it.
I have a 62 and I'm putting in new P&P manifolds soon. The upper is ported to 62, the upper I have right now I don't think is ported to 62, but in the future I'm planning on putting in a set of P&P heads and a cam (still trying to decied if I'm going with a 1161 or a 1280. I know Ben can answer that question when the time comes) but is the 3mm going to make that much of a difference? The LIM I have is gaskest matched
