diffrence in lt1 heads

[MunsterZ28]

what the diffrence between a lt1 head from a 96 camaro or from a 96 caprice wagon? will it fit my car and i would have it ported and polish, found some for cheap just wondering if they can work.

well the z heads are aluminum and the caprice heads are cast iron, besides weight is cast iron not a good thing? and i couldnt find any performance specs persay

[Kwazrollinz28]

yes it will work but why the hell would you go iron?

Aluminum dissipates heat alot faster but also warps easier, it's a softer metal in general. I'd stick with some Z heads.

the aluminum LT1 heads are a different style head than the iron LT1 head on the caprice all together.

the heads used in the b-bodies were designed after the Vortec heads used in 96-98 full size trucks... which are known for being the best flowing SBC heads. So, the iron heads outflow the aluminum heads. However the aluminum's ability to run higher compression, and with the weight savings - gains are pretty much negated and they end up performing similarly.

If they had made an aluminum casting with the votec design, that would be the way to go.

LOL at your sig joe....
