Cylinder Head Question

[Teacher Todd]

The only number I can find on my cylinder heads is 306. Can anyone help me figure what that means. I don't know any of the history on this engine.

1998 Camaro Z28
Automatic



EDIT more research shows that it should be a 806 and that is the early ls1 head. If anyone else knows something different let me know.

Thanks.

Yep... 806 with the perimeter bolt pattern.

best to ask..is the engine modified ? i have not heard of a 306..so i would assume it is a 806 which is stock. the best way to make sure is look at the bolt pattern like bill said.
