69/70 351 heads are the shiznit. Exactly as bob said, theyre cast iron GT40's. My bro ran em on his car. He had em decked enough to get 11.5:1, had some exhaust port work, screw in studs, guide plates, hardend valve seats. With a B cam and exhaust, he was smokin cobras like nothin. And GT's were a joke. He never tracked it unfortunatly.
Blacklx, in case you didnt notice he also removed the smog pump and the a/c (from wat I gathered), that in itself will free up horsepower.

RE: 351 heads (good gain on dyno)
oh lol , i though u meant i stated I made that much,
his motor has been rebuilt and bored over, along with a .035 shave, that scares me but maybe that power is accurate
however, im running low compression for a bower later, so I dont make as much as he does
what i hate locally, is these guys wanting $150 to use thier dyno, and that an azz ripping[:'(]

also waiting list is 1-2 weeks, as bad as i want a slip,[:@]
I was told with my next tune coming after my blower setup, it includes free dyno tuning. $450 tune and dyno, 4 hours min, they told me bring her half a tank full
im thinking of a 6psi boost, im not trying to split my 302, just stuck between 6 or 9 psi

this is no joke man these are real numbers ! and who is charging 150 dolars for the dyno around here it is only 50 bucks for 3 pulls and 100 for 5 pulls and a tune for computer and 500 for a full tune with flip chip by sct!
