They're pretty pricey, do they stack up to AFR 195 heads...which are Cheaper?

what are the numbers advertised by lingenfelter? and how do they compare?

My guess is that they would be as good but you will be paying a little for that name.

Sounds nice and sure they will run good but Id rather have a brand new set of AFRs. Those are smog legal too;larger valves + lighter valvetrain thicker decksetc
I dont see how the Lingenfelter heads arent smog legal they were when cast? :willy:
$300 to remove CNC ridges a waste.

How do the flow numbers & valve seats compare??
