Stock intake valve on eagle is 2.050
Ray,having ported both eagles and apaches do you have flow numbers for both heads measured on the same bench and same bore?
yes at home.
on the bore size, I have tried a couple bore sizes and it didn't make any difference since the valves open towards the center. this is completely different then a wedge head.
off memory
my eagles are 275 @.4, 345 @.6 on my car
Apaches I just finished went 312 @.4 and 360 @.6
another set of Apaches hit 320 @ .4 but will need to be tubed. I was working on them last night.
I have not been able to hit the 370/380s like others have at higher lifts
