Speedmaster Aluminum Heads

There's a thread on them somewhere, as mentioned. I bought a bare set for $502 shipped. Dwayne worked on them a bit (redoing the valve job, milling .055 for 74cc chambers, and Stage 1 porting) and now they flow:

Lift—— in/ex
.100—- 72.5/62.7
.200— 148.8/105.4
.300— 217.6/143.9
.400— 261.8/171.5
.500— 286.1/190.5
.550— 290.5/197.8
.600— 292.4/203.7
.650— 293.5/208.6
.700— 294.3/212.2

Should work nice with my .652 lift cam that is stifled by the mildly massaged iron heads on there now. Will be swapping them on this winter :)
