That doesn't look like a big improvement to me, but I have zero experience with them...... So I don't know how easy or hard it is to make improvements to those heads.
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?
