what is the difference between tfs a-460 heads and motorsport a-460 heads. is the valves the same,chambers,flow, etc,etc

Casting is better on the Motorsport A-460. The EX pattern is dif on some
A-460s some have chevy spacing and some Ford.

not to steal your thread but how different are the vavke placemeant from normal ford heads? Are they ways one can modify trw slugs or does one always need custom pistons to run these heads.

Valve placement is very different so new pistons is pretty much a must. But the HP gains are well worth the investment.

 

[ice-man]

any more budget ones?

Maybe I'm wrong, but I thought it was the other way around. I thought some of the Motorsport "A" heads had some porosity and valve placement issues!
