I was thinking about buying a set of these but the seller doesn't know much about them. They are brand new does anyone know about what flow rating is on them and about the porting and springs etc. Any info is greatly appreciated, thanks Dan
 
I have the stage two (Big valve) heads on my motor, and it's dynoing 300HP without even pushing with the mods I have.

I have the relative flow #s somewhere around here, so I'll see if I can dig them out & post them.
 
I have his heads and cam in my '92 SC.. In fact, my SC was the prototype for his work.. Best dyno numbers were 330.5 rwhp and 402.8 rwtq with an S-model, and stock ported exhaust manifolds. This was done on a DynoJet 248c chassis dyno with standard SAE corrections.

I have more mods now, but that was the last time I dynoed it.

He uses stock size valves, Comp Cams 942 springs (good for .521 lift), and a very good 5 angle valve job.

In my opinion, the best flowing heads for the money with stock sized valves, and his ".520 special" cam is a perfect match to the flow characteristics of the heads.
