No Bronze Guides, Any Reason?

Take them into a good engine machinist and have them gone through. You don't want to mess up your build! 65'
I have to find one. I'm in the very bottom of South Jersey, haven't done any engine work since I've lived here.

Stock steel guides last longer.
I'm not familiar. I thought they were all machined the head casting.

When working on hostile environment engines we found that certain guides were incompatible with certain stem materials
same with unleaded applications
we ended up with hard chrome stems and threaded/ knurled guides
we even knurled new iron and steel guides then ream and hone)
but here we have stock guides that are worn
problem with mopars is getting a replacement guide concentric with the oem guide/ seat
hence using inserts either solid or coils
Shouldn't be too hostile. A street toy with some drag use.

BTW, what is the B3 site? Google didn't show it.

The valves aren't new, but in very good shape.

Bottom line, it wasn't done, and it should have been. The rest of the engine shows no corners cut. Strange. Kinda sucks to have to bury the valves a little bit to fix it.

I need to find a good machinist. I know it's subjective as to where in the country the shop is, and other factors, but what's an estimate of cost to do guides and a valve job? I haven't done this in 25 years or so. I can check spring pressure and of course, assemble them.

I'd love to add Edelbrock's. But it has KB190's. Summit's site says they won't work with Edelbrock's. Anyway, the cost of heads ain't in the budget!
