If you was to have a cam card saying
LS 109
CL IN EX
105 113
Does that mean its a 113 LS with 4 degrees cut in to it to make 109?

What that's saying is, is the lobe sep is 109.

The 105 is telling you they put 4 degrees advance in it.

So you put it in straight up, if it degrees 105 intake centerline, you're good. If it don't, you move / adjust it to 105 intake center line.

109 lobe separation ground into cam
Intake centerline is 105
Exhaust centerline is 113
Install cam at 105 intake centerline to be 4 degrees advanced

109 installed Intake centerline would be "straight up"

People get lobe seperation (LS) confused with Intake centerline (ICL) and dot to dot they call straight up.

I have a 555 and set it up at 109. dot to dot. I ran it about 6 races and it ran from 5.74 to 5.88. After checking I had the wrong valve springs. I pulled the engine out, checked everything. Had the new springs put in and set up and cleaned the head surface. I put it back together and advance it 4 degrees to 105 and ran it yesterday. It was a turd wouldn't run good at all, ran 6.70. All I did was advanced the cam.

Are you actually using an indicator and degree wheel or just going off of the advance keyways on the timing set?
You should have degreed this when the heads were off, you could have actually verified TDC.
If you are just using the marks, it will never work accurately.

Good news is he can still use a piston stop to locate TDC. Lets hope he gets this figured out. That being said, it sure is easier when the heads off.

^^^ Do this. Because TDC indicators are inaccurate way more often than most people think. If you don't have a piston stop, you can easily make one out of a spark plug and a small piece of some 1/8" welding rod.
Also, double check ignition timing, float levels, fuel pressure, & valve lash.

Verify TDC, I've used the balancer as a degree wheel in the past, when I've gotten myself in an awkward position.
