Im throwin in my stage 2's.....I got a valvetrain installed...threw the head on.....now trying to put my cams in....Problem is, when I tighten down the cam caps, the cams rotate slightly...So they're not at TDC anymore....I thought it might be tight valve lash...So I undid all of them, and it still does it....anyone have an idea of why it may be moving? or what the proper installation is??

 

When I installed my cams I didn't worry about the cams rotating while I tightened down the cam caps. Once the caps were tightened down I rotated the cams clockwise to TDC by putting a socket on the large cam gear nut.

^^^this is all i did too.

 

Yup, and if they are not close, simply rotate the crank accordingly (back and fourth) because the valves can run into the pistons.

 

Nice...Im gonna try that tonight....I just got off a 12hr shift today...gonna rest for 2 hours then hit the garage..... Thanks for the info guys...I didn't think about the whole moving the cams by the bolt deal...haha, I feel stupid now...I was trying to move them by hand...
