head's questions hey i have the 853 heads on my ls1 what is the diff. from the 241 heads i have been told the 241 are the better head an they make like 20 hp then the 853. 
Why is that? diff. valves are just better air flow an runners.
thanks

853's stock don't flow as well as 241s but miniscule. When both are ported properly,they're damned near identical. Also there's a casting process difference in them (can't explain that part).
