These are off my 383 and went 11.4's all motor with a CC305 and 10.4's on a 100 shot of nitrous. I just bought a set of AFR's and no longer need them. They were professionally CNC ported by CARTEK. I don't have flow number for them but I by the times they ran I'm sure they flow great. Here are the specs:

-FULLY CNC PORTED
-Milled to give 11:1 Compression Ratio on Stock Engine
-Comp Cams Springs good to .600 lift
-2.02/1.56 Ferra Valves
-ARP Studs

$1050 SHIPPED

I have pics also, PM me or e-mail me at

TTT, $1000 shipped

 

do u have any flow #s im really intristed but 1 problem i doing a blower motor and i need low compression how much will the mill job rais it

 

Dont have any flow numbers on them because I bought a complete 383 from a friend of mine that was switching to a carb motor. They will give around 11:1 compression on a stock motor, putting in dish pistons will lower it though.

That Dosent help me any. how much was the head milled how many CC are the Combustion chambers

 

I remember him telling me they were milled to 52cc and the runners are ported so I would assume they are a little larger than stock.
