and try 69/71 truck heads have a 63 chamber on 302 heads but have big ports//

Look for casting numbers like 'C-9' & 'D-O'.......
Those are really the only ones to try and use......

gt40/gt40p are a better buy they flow more and are easier to find for the same price also the 351w heads have to be milled because the combustion chambers are alot larger

my setup,

but some work done to them bronze guides, hardened seats, enlarged bowls, chopped .010 1.94 intake, 1.6 exhaust valves, stage 3 extreme port and polish job, .600 lift springs, spring coils to prevent any binding, snug fit umbrella's to reduce oil consumtion, head bolt bushings.
takes 2weeks after dropping em off to the machinist




292 rwhp 5,420 rpm after my old tune.

as with any head swap, i now reccomend you have a SCT tune done to remap your system, you will be very suprised what this little 302 can do for you 4000 rpm+ on up.
