aluminum heads ?
 

what is the best make of aluminum heads that will fit a stock ls1?

all ls1 heads are aluminum

wow talk about vague question :eyes:

best heads for a stock ls1....including stock cam....any thing with small intake runners and higher compression will boost performance.
- AFR 205s
- terminator 200cc
- dart 205s


for a "stock" ls1 with a cam....depends on the cam.

more info please

Also for boost, picking up a set of 317 castings will work well, it has LS6 ports with larger combustion chambers.

First pick your budget. Then search on here and the Dyno section and see what H/C COMBOS consistently make power Somewhere in $1100-$3000 range you should find many choices.

i meant to put aftermarket aluminum heads.*

I would say Trickflow or AFR
