I thought they were 61cc stock, but Jon at TSP said that they are 62cc. The heads are decked and chambers are smoothed out which = 62cc in the end.

I just ordered some PRC satage 2.5s, I had them milled .045 to 57cc and had to get shorter pushrods and am going to run a .040 gasket and that will put me right at 10.53:1-SCR and 8.21:1-DCR, on my 5.3
