i was looking at the knurling process and thats pretty neat process, but wow the kits to perform are almost $500. wowza... i think my intake guides are fine for sure.. i get a good suction and pop, but my exhaust valves not so much.. but im also checking with worn out valves so they may not exactly be correct stem size from wear

Can try the wiggle test with the exhaust valve put in upside down, less wear on the valve stem on the top vs the bottom by the head. Then you can try the wiggle test in the valve seat area with the top of the valve stem coming through there for your test. If it tightens up enough without clicking while wiggling, then the new valves should take care of it.

Otherwise take the heads into a machine shop to have the exhaust guides knurled, simple task for them. Bring your new valves with so they can get the fit right.

These are some nice stock style umbrella valve seals, for intake and exhaust with stock style springs.
