Can someone direct me to some flow numbers for a stock set of 340292 turbo heads? They are 2.02/1.60, 64cc angle plug. I'm looking for some numbers to use with Desktop Dyno. Thanks!!

wedge/stock ports and large valves option in the pulldown is REALLY close to these heads.

I have this link that I referr to but can't find the number you put down. This is a GM head? Which one? I found the part number as over counter Lt1 head but I dont have anything to compare to unless you use the 186 head? My guess is the intake ports are something in the 160cc range?

Fwiw, a Vortec will flow a bit more until the turbo is ported and then look out!!

Thanks guys. The "wedge/stock ports" should get me in the ballpark.

they flow mid 200`s box stock. I had a set with 2.055/1.6 valves fully ported that flowed 280`s at .650 lift. I think they are great heads but almost everyone else will tell you to go vortec or aftermarket.

Try here for I think the Phase II head??

At least I think the -292 is a Phase II head????
