Good point on the standard Magnum heads. Is this worth doing with standard Magnum heads? My combo is stock 360 (low comp) with XE268 Hydrailic cam, wieand intake and Demonsizzler TQ plus TTI headers and 2.5 exhaust. I currently run J heads with 2.02/1.60 and home bowl port. I shift at 5600 rpm. I figured the compresiion gain would be worht the swap?




stealth or action plus? if it's the action plus, I'd go with a stealth or RPM/air gap. with the magnums, I'd do a good 3 angle job and a little bowl port/cleanup as well. you'll gain alot on the compression, and you'll get the same flow with a smaller valve/slightly smaller port, which should really help low end torque.
