header heat shields

[joebarthlow]

My heat shield over my header is rusted and rattling. It's the lighter metal one on my '74. Will the cast aluminum shields from the '73 and earlier fit as a replacement? The holes look to match up. thanks

Just a thought, I’ve been through a few over the years, and grew tired of them rusting, now I have silicon leads and plug lead socks that are heat proof and cover the wires over the manifold, next will be ceramic coating of the exhaust manifold, I have a Tii and the bolts which go into the manifold are sheared, so an easier route would be a e21 exhaust gasket / heat deflector all in one.

sorry didn’t really answer your question ?

interesting ideas, none of the less

Yeah, the aluminum one works, too.

 

I recall one hole might need to be drilled and tapped in the 

manifold, but no promises...

just runs the E21 manifold gasket.

What exhaust manifold are you using?

 

If a Tii manifold, the aluminum heat shield will fit (with spacers on the top two bolts).

Regardless of which heat shield you end up using, employ stainless steel bolts (6x1 mm thread) and plenty of anti-seize paste on the threads so you won't snap bolts off in the manifold.

Personally I'm a BIG fan of the E21 gasket/shield combo.  Granted it subjectively isn't the nicest looking thing, it's cheap, readily available, works well, and doesn't add anything extra to the rusty-hardware tally!

New OEM version Hex bolt with washer part # 07119915057 is better option IMO. You still need to apply anti-seize paste on the threads.

Ceramic coating may help with the heat.  Just a thought.

good input, thanks!
