Cylinder head porting and flow

I know of some flowing 306 ex. and 287 in. Theres probably higher flowing sets out there that's just some I know of.
+1 Even if you don't purchase heads from Guy he'd be the one to talk to about the flow capabilities that can be achieved.
http://greracing.com had mine done by Jim at Galto racing picked up 30 cfm intake and 60 cfm exhaust.:thumb:
All i can say is the trucks i have installed these on they are more responsive and show good results, i do know he said multipe orders at the same time cut down on set up and they can be done cheaper.Also to help any members here i carry all the differant heads so down time can be kept to a minimum.Jim and i bartered so i wouldnt be able to pm any price per say best bet is to give him a call or e mail,i do know he is looking to advertise and get the heads out and if people want to dyno before and after with out any other mods to tell real world #s i know this is something he really wants.Mine was a complete rebuild and alot of other things added so for me to post any #S is not going to prove anything.
I am currentlly trying to get him to become a vendor here so if enough intrest is generated that would be great.
On a side note if you are running stock manifolds,profabs,(not sure about PPE) your manifolds will need to be opened up to match the heads.i had a set of ATS manifolds and they were perfect matched from the factory.I wasnt able to run them as i was running the stock turbo at the time and couldnt get the clearance between the down pipe and the massisive uppipe from the ATS kit.Now Eric (Wisconsonhick1) is enjoying them.They would be awesome for the twins now.

Those were done by Jim. He has done a few sets for me now I got to know him thru Scott. I have the flow sheets around here from 1 or 2 mild ported sets.

any chances of us guys running the real Dmax engine to get the screw in cups?
