Thermo-QUAD!

I'd rather do a slight cut to the head surface. Around 9.0/9.25 to 1 compression would work nice on the street; the heads are '91 360 swirl ports from a 1-ton van. A magnum swap would entail more cash and complications and this is not to be the final motor for the Valiant, it is the inbetween one! I have a '72 cast 400 (w/ a core numer of 1) and a forged 440 crank resting comfortably in my shed for when the time is right for a proper build up of a REALLY good powertrain :thumbup: .
