What head bolts do I need?

[stupotarnie]

Hi guys, Im about to buy head bolts for my ls1 vu ute, But not sure what type I need. Not sure if I need the early or late type, And would they be a different length or same length? Engine has 241 cast heads if that helps.....................Cheers.

You need the early type with the shorter bolts. ARP wont have them till mid october so if your in a hurry might need to shop around see who might have them. or go genuine

Early ls1 had half longer. Ls6 block all short iirc

What year / month / model did they change to the late type that are all the same length?
