I messed one of the valves up when cleaning by accident, most likely will be purchasing new valves. I know I can buy valves from ebay, jegs etc. But I really don't want to be sent the wrong valves or springs if i get a kit, if that's even a good option. Ebay had a kit with the same equipment, except the springs had different seat pressure not sure if it's a huge deal, but that's why I'm asking. Here's the Ebay links;

Not sure if the info on those sites are accurate, but one had z28 and the other not. I'm not sure whether they had a non-H.O. for an '83 Z28, AAhhhh I'm confused.

 

It does not matter if it's a z28, H.O, trans am, 1LE, etc etc.

It's a small block chevy engine.. All you need to know is the valve head size. Stem size is 11/32" and exhaust valves will be 1.50", intake could be 1.72, 1.82 or 1.84"

Measure across the valve face, or get the casting numbers off your heads (in area under valve covers, between rocker studs) and post here or look them up on google. The casting # will tell year, engine, chamber size, valve size, etc

Those ebay ads says Elgin parts, elgin is a pretty good brand. Not high end but good replacements for sure.

You do not need the .550" lift valve springs unless you are pitting in a bigger performance cam
