What is "reverse cooled"? I ask this question because of the description on this add. First it says it's for our engine, then in the bottom description it says it is NOT for reverse cooled engines? Is this a misprint? Can someone explain?http://www.gmpartsdirect.com/results...ges=1&pkgid=33
93-97 LT1s and LT4s were reverse cooled meaning the coolant routes through the heads before the block. it seems pretty clear to me that the ones in that link are just SBC heads. mabye have the same size runners as the LT4 heads?
2 different parts; the LT4 head with the 2.00 & 1.55 valves included has a tiny picture and a very short desc. (GM PART # 12363287). The other one below it w/ the big pic and long desc. "fast-burn, not for reverse cooled" Fast Burn head is the next part listing (GM PART # 12464298). Looks like a hell of a head for a Gen I SBC build, though...
