318 magnum heads

3404spdfish said

is it worth the effort and money to use them. somebody put 69 J heads on the 76 360. just going from open to close chamber. I am a J and X head fan. my 67,69 barracuda's run them and I know what they will do. I was wondering if the swap would be better. 318 has somewhere around 1.92/162 valves is it true that the r/t magnum heads came with 2.02 intake valve.

I will let you know how mine turns out. 72 casting date 360, all stock bottom end with new oil pump and windage tray added. Summit 50052 flat tap hyd .454 [email protected]"/272adv. cam. The summit lifters are amc compatible so they have the holes for pushrod oiling. Magnum timing set w/tensioner. 318 magnum heads.

To install these heads I got these parts:
Trickflow 7.650" pushrods. Hughes 1199 magnum spring kit. Professional Products Crosswind intake.

With the magnum 1.6 rocker ratio, my cam should be .484" lift. If you keep a stock 360 cam, keep the stock magnum springs/locks/retainers and save money.
