Not regarding my 77, but in general, are heat shields really necessary, they always end up rusting and rattling! Dangerous to remove?

IMHO, OEMs don't install anything "extra" that doesn't decrease their warranty expense. The purpose of shields is to control heat that otherwise will soak into and damage wiring, spark plug wires, hoses, floor treatments, oxidize fluids, etc, and to decrease liability resulting from fires. In other words, each situation demands independent evaluation with the acceptance of responsibility for any adverse consequences that result from shield elimination. Consequently, there is no valid "general answer."

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

Ok, fair enough. I’ll replace the darn thing. But, why not just make them out of thick aluminum or galvanized steel and add an extra $25 to the sticker price? Thanks bd

I agree with bd, just suck it up and do what you can to eliminate the rattle...

Yes, i think they are necessary. i threw away my 4.3 shields, emission control junk and other "junk" thinking i would never need it.
Well, i had a problem re-starting after driving a few mins---after getting gas or food etc. i found out that the downpipe on a stock 4.3 exhaust manifold is DIRECTLY next to the starter.
Installed a flexible velcro-type heat shield (from Taylor, and i recommend Taylor products) and problem solved. If you're concerned about squeeks and rattles then you may want to try one of these flexible wrap-type shields:

It's and easy install, but one disadvantage is if oil gets on it then it's a big mess and there's really no way i know of to clean it. So, i've actually had to get a new one. i had a leak around where the dipstick goes into the engine----and, of course, it's on the same side as the starter......
