360 short block suppliers??

Moper, yes I bring the 30 degree on down to the top of the 45 angle. Right to the edge of it. Really picks up the low lift flow and gets the air moving in the port sooner in the lift cycle. I remember the early Poncho heads had 30 degree seats and showed great low lift numbers but this hurt higher lift flow a little, flow numbers over .500 or so. I do this mosty on street/strip engines with lifts in the .500/.550 range. Hemi heads like 37 degrees, some will like 35-36 better depending on combo and volume. The bike heads I do I usually put 37 degrees on the valves (hemi 4 valve) and they show good flow improvement with that. Be a good help to those who are putting together a street or torque motor and it is a cheap/easy mod. No down side to those with less than .500 lift cams. Full on race motors probably won't need it. Anyway, Moper..give it a try and let us know what you think..good topic. Thanks, Terry.
