val and val. job??? for the head guys

better multi angle valve job is gonna pick it up for sure.
Skinny stems and less valve in the way will also pick it up.

If you flow them after, I think you'll see a gain of 10-20cfm up till .450-.500 lift.
depending on the bowl/short turn shape/pinch cs, maybe hit 260cfm.jmo

but really, with a macinni ss semi tulip 2.02 intake and just a lil short turn and pinch work and minor roof kink blending I had [email protected] on the intake.not much work there.
