Is there any difference in performance between the Lightning Heads and my current 04 GT heads? Or are they the same PI Heads



Thanks

Seems to me like there has to be some difference or all the SOHC peeps would be throwing that blower on there stang.

lol i'm not interested in the blower, i'm wondering if the heads flow any better

they're just plain ol' PI castings... usually with too few threads in the spark plug holes. Keep your 04 heads. If you want improved flow in modular heads you have to either port them or replace them with heads with a higher total count of valves.
