according to smokemup.com nothing. http://smokemup.com/tech/ls1.php but, from what i've heard, stock vs stock, the 241 flow better. once ported, all bets are out the window.

also i have heard that right under ur spark plugs on some heads there is a lil triangle. if you have those then your heads are suppose to be stronger. the triangles are a bi-product of how the heads were casted...dunno though thats just something ive heard
