When a head is milled how do you adjust/check your timing? Do you set your base timing a couple degrees retarded, or advanced?

 

milling the head retards the cam timing... it's about 1 degree every .015 taken off the head

hmm why would it only retard the exhaust cam timing and not the intake cam?

what are you asking?

 

It alters both intake and exhaust cam timing.

thats a good approximation. Varies slightly from setup to setup and belts, etc...but it's a good guide

I was spacing earlier...it's about 1 degree every .015 taken off
