noob valve spring question

The simple way to see if the cam is even close is pull the drivers side valve cover and roll the engine over until you are on OVERLAP of number 1. That is 180 degrees from TDC on the compression stroke.

To make it less murky, roll the engine over until you are a TDC on the compression stroke, and then turn it one more full turn until the mark on the damper is lined up with the zero on the timing cover.

Then look at the intake and exhaust valves. If the intake and exhaust are open the same amount, the cam is in straight up.

If the intake is open more, it’s advanced.
If the exhaust is open more, it’s retarded.

The greater the amount of difference the greater the advance or retard.

My thinking is the cam was never degreed and it’s seriously advanced as PRH said many posts back.
