Stick with the 6.0l heads, they have a much better port design. The ports on the 317's and 035's are the same as the LS6 heads (243's) only the chambers are bigger. That's just my opinion.

If you're not looking for every ounce of power the 241's will be fine. They don't flow as well in stock form as the 317's, but on a FI engine, cylinder head flow won't make as much of a difference as it would NA.

I don't think the .5 will make that much difference, but then again I'm a FI newbie myself and have never driven a FI car with compression that low. Maybe someone with a bit more experience will chime in.

i didnt cc them but doing the math, about .007 is approximatly 1cc so i shaved off about 6.4 cc so. the average cc of the heads being 71-72 put me about 65.5 or so
