Checking valve spring heights.

You can buy a seal cutter and pilot for probably under 50.00 if you shop around. Then you can trim for positive seals and lower the guide at the same time. You can do it by hand.

I'll admit, I've seen them for chevrolets, but never really looked for one for a Chrysler. I've never used one before.

Thanks for the heads up. I'll take a look. Thanks. Eric

Same cutter. Different pilot. I cut the guides to .500 and then use the correct seal. That means you need a .500 OD seal cutter and a .375 pilot. If you want to do other stuff just buy a .342 or .312 pilot.

I figured I'd follow up my results in this thread, since this is where it all started. Lol.

Got the head, old gasket, and new valve springs on one cylinder all mocked up.

Made two lifters.

One at zero preload

One at .050 preload.

Exhaust lift "net" at retainer came in at

.430 exhaust /.419 intake.

1.57 installed height exh
Minus
1.10 coil bind
Minus
.430 net lift at valve
Equals .040.

Looks like we will be closer to coil bind than I am comfortable with using factory stamped steel rockers, cheap springs, and factory pushrods.

New exhaust valves are in order.

Thank you everyone for the help and input.
