Yep, that would be good to know. I ordered new valves for my 273 and didn't pay attention to length compared to the stockers. We had to shim the heck out of the springs and I had rocker sweep issues. SOmeday I may pull the heads and straighten that mess out. May be. But if it ain't broke..............
Melling says 4.974 for my 273 intake valve. A different brand is 4.979. Melling Exhaust is 5.003
