I couldn't find the flow sheet when I went to the shop today, but when I talked to Jim today on the phone he said ~350 on the intake @ 0.650". I'll get the sheet after the holidays.
He said ~125. Also, after the holidays I'll have definitive answers.
Just trying to give you guys some idea in case you have to make decisions soon.

Talked to Jim Xmas eve and pretty certain 119cc. They sound like an awesome set of heads. Somebody would get a great deal. I asked also about another set but he didn't believe he had another set of matching castings. I actually am interested myself but need another set. You can't hardly get the parts for the price let alone the time that went into them.

Truxton, He doesn't have another set, but he has a couple sets of the EQ320 that he can put together relatively cheap. They are great heads with good flow #'s.

I forgot about the unshrouding for the 2.30 valves and other good guy grinding. I bet they looked good. Rookie he was telling me about some new head that was suppose to be all as good as profilers but we had bad cell ph reception. If you know what he was referring to pm me if you would otherwise I am going down to ship engines next week and going to stop by.
