per the NHRA flow #s, they are pretty good, right there with the best of them.

I have the same heads on my LS5

1972 402 240hp,300hp,330 hp,LS3
454 open 365 hp LS5 113.0 cc
actually the 1972 LS3 used the '2292' head.......very similar to the 241

I think the 241 was 454 only.
from what I've seen

I don't see why not

they are almost identical to the 241's that came on 454s

check the NHRA website for the flow#s
