Did Direct Connection offer a factory ported iron head? They have a lot of W2 characteristics. Bet they flow pretty well.


Yes, stock (360) heads. IIRC, they were the 308 castings, which have W2-ish like exhaust ports. I could be wrong. The heads came bowl ported and the next level up, fully ported. That was there description with a % number for flow increases. But there was still room to go on the heads. They also listed the heads for there intended lift use. AKA; Up to .500 and then over .500.
MP also offered a ported 318 head, the 302 IIRC which they claimed it out powered the 360 head by 55HP on the smaller 318.

MP offered loaded W2 heads, but not ported, at least that I remember.
