I got some..you could find some from a pull yourself junkyard too but while your at it get 049 or 781 big oval ports from 73-74 fullsize Chevies pocket port them and slip some 088 head valves and you got 50ft.lbs of torque more thru the whole lower rev range plus they can handle a 496 turned up to 6500 rpm at 650+ hp with ease and be head to head against 088´s from 4000rpm up being superior lower.
Justa budget tip from here...
And yes I got a pair of those good ones and peanuts from cars that used antifreeze.
I have a set of GenV heads. They have a port and pollish job. Fresh valve job, casting flash removed, chambers are pollished. I'll trade them for some 7208 glass.
