Spark plug heat shields

I just finished installing Banks Torque Tube headers on my 1999 Itasca P32 with Chevy 7.4 litre engine.

If I don't re-install the spark plug metal heat shields, will that cause problems with the plug boots? I can keep the wires away from the headers but worry about the boots melting?

Thanks in advance...

Engine builders don't spend any more $ or time then they have to, put them on.

I had heat shield on my 3.9L Dodge. If they are hard to put in; up a little anti seize on them.

I put "header wrap" insulation on mine. No plug wire problems.

The factory wouldn't have put them on for nothing. If they don't fit the wires, use the wires that they fit. By the way every 454 that I've had was hard on wires and cap & rotor. Change the cap & rotor every 2 years, they get corroded inside and are very hard to clean up. I always used a brass terminal cap from Napa, but they still get a build up on them.

So I drove it 130 miles without heat shields and after it cooled, looked at the plug wire boots and they looked fine with no melting or anything. But, to be on the safe side, I went to local parts store and they wanted $20 for 2. That would be $80 for a full set. Well, I went on eBay and found a set of 8 rated to 1200 degrees for 11 bucks shipped. Should be here in a couple of days. Here's the ad for them: BLACK 8PCS 1200 SPARK PLUG WIRE BOOTS HEAT SHIELD PROTECTOR SLEEVE SBC BBC

I'll post whether they work or not...

I have an 8.1 that has had Taylor plug wires already installed before I got it last March. The fiberglass boots are on them but they also have splayed aluminum shields around the insulators that keep heat from the exhaust manifolds away from them. I assume they are a GM item but one on #7 is missing. No web searches have found a source of them to replace the missing one. Any hints for replacements? I discovered it when I replaced my plugs. I went with AC 41-101 iridium instead of the original 41-983 platinum. I also gapped them at .045 instead of .060. I will find out next week if it gains any performance. It had started getting lazy climbing hills. I also changed the fuel filter. I also have to replace the heat shield on the driver's exhaust manifold as it had corroded around the bolts and was just barely hanging on one of them.

If I can't buy it I'll make it.

Don't tell me I can't do it, just tell me it won't be easy.

Rockauto had the heat sheilds.... Plugs & wires will NOT give you any performance gain per se.

there are better products out there like Titanium socks for the boots if you have headers. Stock plug shields for my 89 454 don't work with my Hedman headers.
