What do they flow when you port them?


On 2 moparts member heads they went
.4 312
.5 340
.6 350

On mine, but mine are tubed at pushrod pinch. Mine go
.4 320
.5 345
.6 360

I try to do value porting. I have like ADD or something. For what I charge, im only willing to spend x amount of time. The amount of time to get that little extra whether its the g3 heads or LS heads people just dont want to pay for and I really dont want to slave over them.

Dwayne, what do you think about the radius on the intake seat on these CNC heads I posted?
