if you have dished pistons, get a cam with short duration and semi high lift, will give you a little better low end torque, or just an rv cam approx. .465 lift will do and don't forget to gear up the rear end to some 4.11's or atleast 3.73's. some headers with a 2.5 exhaust size, or some corvette ram horns with the 2.5 exhaust manifolds, a fluid dampner will help some, electric fans help, and an electric fuel pump helps a tad but not necessary and last but not least a good oversized air cleaner, air in, air out. it also kind of depends what you want, good torque with a 5500 redline, or better top end around a 6500 rpm redline that picks up around 3000 rpms, 1.94's aren't bad, not the best but they can make pretty good power.

Sounds like the same truck engine I have. Should have heads ending with casting numbers 991. They make good torque, but are not high horsepower heads. You could look for some heads ending with casting numbers 041, they're versatile good performing stock heads. Or convert to vortex heads and a new intake. Lots of options, how much you want to $pend?!?!

Your original heads (1969) may be 441's.(not sure about trucks) They are about 76cc. To increase compression you can use any number of heads to raise the compression. 461,462, 291, 040, 186, 492, and 041. The last 3 have bolt holes on the end for the alternator and other accesories.

These heads are; 462324 stamped on top of heads and there is threaded holes on both heads. For attaching other brackets, and the like. "Quadrajet" built by carter.No other numbers except on the butterflies.(back barrels).:blowtiedb:
