I just bought some 6.0L heads, was looking at them and noticed where the rocker arms mount looks a little different than my 241 castings. Will my 241 rocker arms work on these 317 castings? I only ask because I am using the harland sharps and want to know if I need to sell them. The heads were out of a 2002 gmc 2500. Oh one more thing, are all 317 castings the exact same?

 

No one has any idea?

 

rockers should work might want to double check pushrod length.

 

LS1 rockers should work fine. And a 317 is a 317 is a 317...in other words no differences.

 

Awesome!! Thanks guys!!!

 

what is the difference in 317's and 241's

I have set here and they dont look much different, bigger etc.....

 

Really the only difference is the 317 has a little bigger combustion chamber. 72cc vs 66cc on a 241. Well I have heard they flow a little better too. I am using mine with a procharger and sending the heads to TEA for a stg 2 setup.
