I have ported a number of heads and those Crane ported heads exhaust ports are always round and Huge! My hand is cramping just thinking about those ports.....

I have always like a D shaped exhaust port, with the floor filled in as it helps with reversion and increase port velocity.

Really nice heads though, I would be interested in mounting them on my Superflow bench and see what they flow.

Wow just read through this thread. Very cool looking heads. Rob

Thanks Rob, I still have them if anyone is interested, Rob.

Rob,

What size Intake valve? 2.19 or 2.25

Hi Sean, Thanks for your interest. I should’ve had that info in the original ad,Rob.

Intake valve: 2.300”
Exhaust valve: 1.880”

..... Somebody is going to get an awesome set of Crane Super Port Flow Heads! ••••SOLD••••
