'87 head specs?
Chasing engine rebuild and keep hitting a few stoppers due to lack of spec, as in what size blah to use.
I'm going to replace the valve guides and valves in the heads, expected the FSM to have information here, no luck. Checking Rockauto, as good-old-usual they have various options. Problem, the various options have all kind of sizes.
Do I need .50" or .55"? Spiral? 2.125" or 2.25"? Some of this I can measure, some I can't.
How do I find what dimensions and such are needed?

Yeah, did that before and they failed to replace the guides (and what else?). I'd rather do most myself, though I know replacing the guides needs to be a machine shop. And pick my own parts.
