These are Ultra Pro Machine billet heads CNC ported.
Other than a few scratches they are as new.
One has water jacket the other is dry. Would be great for an alcohol drag race application.
No seat job done yet. Will take intakes of 2.125 to 2.180. exhaust 1.6 or 1.625
When seat job is done the intake flows about 355 cfm at 0.800 and the exhaust about 260 (no pipe)
$1050 for the pair.
PM me if you are interested.
