The engine shop that built my motor told me they had to advance the cam 4 degrees positive. I have an adjustable roller double roller timing chain. I have always been under the impression that when cams are installed in the LS1 they are installed straight up. What does degreeing the cam actually do? Does it change the timing or lsa or anything like that. My cam is the Comp Xer 224/224 .581/.581 114lsa. Please advise.
Thanks

Degreeing a cam is a way to check that the valve events match up to what the cam grinder intended. When you advance or retard the cam, you can move the peak torque up or down in the rpm band.

That cam comes 4 degrees advanced already. Advancing it further will kill power & make for nasty low-speed drivability.
What you should do is retard the cam 4 degrees so that it is truely 'straight up' & not just dot-to-dot.

Degreeing the cam takes a degree wheel & a dial indicator with a way of mounting it.....& a piston stop so you can find TDC on the #1 piston. After degreeing in a few LS1 cams using Rollmaster 9-keyway chains I would advise EVERYBODY that has one of these chains to degree in the cam as it is very easy to install the cam incorrectly which could be a fatal mistake.

Proper valve events for that cam (as ground on a 110ICL):
Intake valve open: 2 BTDC
Intake valve close: 42 ABDC
Exhaust valve open: 50 BBDC
Exhaust valve close: 6 BTDC

My advise is to install it on a 114ICL for these valve events:
IVO: 2 ATDC
IVC: 46 ABDC
EVO: 46 BBDC
EVC: 2 BTDC

Check out Compcams & Cranecams websites for instructions on degreeing a camshaft.

Each cam should come with a card like #'s 93 pony listed.
You have to have the card for the cam you are degreeing in.
The #'s change for different grinds.
Only use the card the cam came with.
