Intro to a port job

.
Would a bigger intake bring it back up enough to not need new seats?

An chance they cut a spring seat in to a water passage?
Its 2.020...and there is a well around all valves with a sharp edge that could about cut your finger open , 2.05 vs is +.030 รท2=.015...so no imo, because the well is roughly .020 larger.
I'll have my guy look them over and see about a throat and chamber side.
