Does the '60 model use any form of heat shielding for the ignition wiring that runs behind the exhaust manifolds?? I'm not speaking of the EM shielding... I'm asking about HEAT shielding such as the '57 Corvette used??

My '60 didn't have any (doesn't mean it never did) but I had to make shielding between the middle 4 plugs and the exhaust manifold because the spark plug boots kept melting.

Do you have a picture of this for 1957? OR a link to where it can be purchased?
Yes, all the parts houses have these parts for '56-57 Corvettes/passenger cars.. I'm trying to determine if '58-62 Corvettes used anything like this for a similar purpose?Spark Plug Wire "U" Heat Shield Kit (Banana shields or 'boomerang' shields) protect park plug wiring from exhaust manifold heat...Paragon Number: 3266K GM Part Number:
Spark plug wire lower “U” heat shield kit, includes (2) shields and (8) grommets. Years: 1956 - 1957 Condition: New Packaging: Kit Type: Stock

I am a little confused by both your 1st post and this one. I don't know what EM shielding is? The shielding for RF to shield the radio from ignition noise is the only shielding I am aware of. I don't know of any HEAT shielding on these cars. I thought maybe I was missing something on my 57 but the parts you have shown look to be part of the ignition shielding that bolt to the block that I recall on several of the old Corvettes I own.
Although these parts are referred to above as HEAT shields I think they are actually just radio shielding as they contain the plug wires encased and bolted to the block and would be as hot or hotter then if they were exposed to the air.
Maybe someone can clear up this confusion?
Those are the ones that go over the top of the spark plugs and plug wire boot. The others shown above are for the plug wires BEFORE they reach that point. The original plug wire sets for these cars are very long and run down the back of the engine under the shielding top and side pieces and then route through the other pieces shown above that bolt to the block.
Bama,
57’s had the boomerang shields, 60’s did not. 60’s used a clip on each side that attached to an oil pan bolt. That kept the lower portion of the wires against the block and away from the manifolds. Then, on the same 1/4x20 bolts that hold the 4 brackets (pictured) to the block, there are small 3-fingered clips that also hold the wires to the block and away from the manifolds.

Thanks Mike! This is the information I was looking for!

EM shielding = another term for RF shielding. "EM shielding (electromagnetic shielding) is the practice of surrounding electronics and cables with conductive or magnetic materials to guard against incoming or outgoing emissions of electromagneticfrequencies (EMF). EM shielding is conducted for several reasons."
Actually the lower banana/boomerang shields (for '56-57) were actually used on metal passenger cars also, and were for 'heat shielding' as opposed to RF/EM shielding (although obviously they would serve to help that function as well). The purpose was to keep the wires from touching the HOTTER exhaust manifolds (read 62Corvette's post on this topic)...
I'm familiar with the '56-57 lower heat shielding, but I'd LOVE to see a similar photo for the small bits installed which held the wires away from the exhaust manifold/pipe on '58-60 models. I've ordered the parts (per Paragon) but haven't seen a photo of them installed... anyone?

No one has a photo of the installed lower ignition wire retainers for '58-60 models???
