Checking valve spring heights.

.060 minimum

Yeah. I think we're screwed. Lol.

I had Dad take some "spitball" measurements with the caliper he had on hand, (I brought my good one home with me for use on the tranny rebuild going on in my garage).

He came up with .435 exhaust, .540 on the exhaust.

I'm going to take my caliper over there Wednesday and double check, but it looks like new valves are going to be a must.

That's hotrodding. Lol.

Thanks again everyone for all this help and info. It is greatly appreciated.

Thanks. Eric.
