Smokin low has it buy the balls,If you still have 3/8 valve stem diameter find a machine shop that knows what the hell they are doing and make a set of 1.88 valves to work, buy the time you do the math and try to find a 1.80 valve you will have missed a month on the water. Not trying to be a smart ass but I,ve been down the 429-460 road ALOT. M

You first need to check OAL and Tip Length of the valves currently in your heads and then find a match, but generally:
  • Ferrera F6159, 1.800", 5.058" OAL, 0.250" tip (this p/n also works in a D3VE-A2A head as a +0.075" valve)
  • S-I 2101E-S, 1.880" (dia. must be cut to 1.800", as your lathe's cutting bit shrieks in pain), 5.073" OAL, 0.250" tip (this p/n also works in a D3VE-A2A head as a +0.100" valve)
  • S-I 2106SG-S, 1.800", 5.073" OAL, 0.350" tip (<---you might need +0.xxx" retainer)
1.800 exhaust, eh? Hope you're no bigger than a 2.19" on the intake side and don't have too agreessive a cam (big lift/dur with a tight LSA). Assuming bigger than RV cam, the general rule of thumb over here is 0.060" between the intake and exhaust valve heads...if you don't have that, then turn the heads or sink the seats a bit. By the way, in regards to your 3 bent valves, you might want to make sure that the reason for the bent valves is not relative to what I am discussing in this past paragraph.

Oh, and one last thing:



How dare you photoshop your avatar into a negiative. For christ's sake stop messing with all of us and make it back into a full color image like it should be.
