Checking valve spring heights.
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.
