Question about my new Stg 3 heads that just arrived
Just got my Livernois Stg 3 243 heads delivered today. They had a tag on them that read:
"Ex tips at 0, In valve tips are .025-.030 below 0 - check your lash & adjust accordingly"
So as I understand it, with my factory rocker set up, Im setting these to zero lash, measuring the pushrod length, and then adding the preload for the LS7 lifters to get my pushrod length. With the intake valve tips sitting below the exhaust tips, Im assuming that Im going to end up having a slightly different length pushrod for the exhaust and intake valves?
Any help would be much appreciated

Thats how I read that. The intake valve is sitting lower than stock. Not a problem you can't solve. When you measure for pushrods, your intake pushrods will be shorter than the exhaust.

I couldnt tell you exactly what to expect. Your not altering the height of the rocker, so I wouldnt think so. The important thing they are trying to tell you is you can't just throw your stock length pushrods in and go. You need to measure.
