Cam degree..

I've mentioned this on my restoration thread but I'd like to try and get a little action here. It's saying 108 on the intake with a 112 separation center line and a 116 on the exhaust. So I'm shooting for this 108 and I'm getting 110 to110.5..
I'm thinking of just letting it ride as I'm under the impression that I may lose a couple degrees just with the timing chain stretching?.. I do have a multi-key lower gear to advance and retard but I think this may be just pushing the limits of what's really needed..
Help and opinions welcome thank you for your advice..
Use timing gears, they dont stretch.
I have never installed a cam retarded, you will lose cylinder pressure.
Maybe that's what you want?
