i dont really know much about heads but would it be worth it to pick up these heads there pretty cheap heres the specs assembled 241s milled .030 (62cc), 2002 intake valves(2.00) and 98 1.60 exhaust valves with some bowl work/ bowl blending, unported runners. Flows roughly 255-260cfm at .600 lift.(more than a stock ls6 head) would they work with mods in sig and how much power should i expect i made 390 now on a mustang dyno

 

???????????

 

unported 241s flow 260 cfm? wow you have some factory freak heads there bud. what is your question exactly?

 

i was wondering if its worth it to buy them,they will cost me like 350. i was wondering how much power i should expect on my setup
