10-19-2007 Each one has an adjuster, so you just work your way down the line adjusting. The best way is with a flow meter, but you get plenty close enough buy backing out the idle screw and ajusting them all to be closed, the slighty better way is to crank in the idle screw and set them all to so small opening using a shim (like a small allen wrench).
Yes, they are 4 vavle heads. I measured the cams last night, they appear to be the same lift and duration as 328 cams. I may save the couple thousand dollars to weld and regrind (intakes only, the exhaust cams are fine) and see how they do stock. I suspect the 512TR cams are the same as 348 cams, so more lift and a touch more duration....I may see if I can find a set, I want the lift, but I don't want more duration. I'll have to think about that and may just stay stock for now to keep expenses in check.
edit - I just plugged the stock cams into the simulator and it things I'll go from 554 with custom cams down to 550 with stock....that seems like an awfully expensive 4 hp.....stock it is unless something changes with the head flow or Russ's dyno graph (328 engine, ported heads, custom cam) is just so good I just have to copy (the simulator isn't prefect so the 4 hp could be 14 or so)
