Located just south of Monument. Head is complete short of a valve cover, block is stripped bare.

Any idea of the year of the head/block?

Nope. How can you tell? Casting numbers?

Yes - the casting number on the top of the head on the driver's side, outside the valve cover area - should be 5 digits - 60020 - something like that. The block (if matching) should have a regular engine production number stamped near the distributor - like 165728. Either one or both would be useful. Thanks - Steve

The head has a casting number 60051, and the driver side of the block has a casting number 60032. I can't make out the stamped number next to the distributor, but if you really need it, let me know and I'll try etching the rust off and taking a rubbing with a pencil.

I can't find that head casting # on Mud, so the stamped number by the distributor would be most helpful - it should be Fxxxxxx format. - thanks!

Looks like a 73 or early 74 block. Serial nimber is F536859

I'll take 'em both - or just the head, if you or someone else wants the block. I sent you a PM.

What are you working on Steve? New project rig? :)

My '77 engine in my '78 FJ40 suffers quite a bit of leakdown of oil past the valve stem seals. Hard to start on cold days and big clouds upon startup. Nasty ash deposits on the plugs, too. I had a set of FelPro valve stem seals installed in 1991 - not sure why they have failed so soon ;-)

I'm considering either using an early head, or shaving a '77/8 head and having a valve job done to tighten things up. My compression isn't terrible, but a wet test shows that the compression does not improve with oil, so I suspect the valves are worn, too.

The '83 2F in my FJ45 was stronger and slightly smoother, and I miss that sensation in my FJ40. So, this would be just a mild warming up of the current rig.
