This isn't an interference engine is it?

I'll either borrow a bore scope from a mechanic buddy of mine or just pop the head off later next week.

Honestly, I don't know. But I would be prepared for additional damage, just because that's the way it always seems to work out, especially when you buy something already broken and the seller says it "probably just needs" blah, blah, blah...

It is interference.

Just pull the head. It has to come off anyways.

None of the poll answers. I didn't vote.

Depends on your financial condition, how many miles are on the engine, and whether you plan to keep the truck long term.

If it's high mileage, you have the cash, and you plan on keeping the engine for a bunch more miles (and the truck is otherwise in good shape) I'd probably get the reman'd engine.

If it's fairly low mi., you're cheap or broke, and you're planning on selling within the next year, just get a valve job on that head and a new rocker arm and lifter.

Well we came back from a weekend trip to find that a water line in the attic had spring a leak and caved in the ceiling so looks like the truck will just have to wait for a little bit longer...

I finally have time to work on the truck again! I've pulled everything from the intake up and all of the stuff on the front of the motor. I'm about ready to pop the head off and do a visual inspection.

Do you guys have any tips for me before removing the head? Any one way better than another to keep my timing if I'm going to throw a new head on?

IMO, I would replace both heads. But that's just me. If you feel so inclined, get a piston ring and bearing set, and re-ring them & change the rod bearings. It's more time than money to do so. If the pistons are in good shape, you replace both heads and the bottom end bearings, that pretty much leaves the bores as the only unserviced item. And you can check those with the pistons out. Unless they are way out of range enough to yield piston slap, I would call it good there. You might even be able to order a bare head and swap the cams, springs, valves, and rockers over.

It put a pretty good gouge in one of the cam lobes and chewed up one of the rockers so I'll probably just get a head (or possibly heads) that are already loaded. I could probably smooth out the cam lobe, but it seems kind of risky to me...

What about the timing set? Kits range from $186 to $632 plus shipping. What parts wear out on these and what should I not worry about?
