Any advice on how to best shield my starter from header heat on my 350 chevy YJ? Going thru starters about every 12-16 months.Even had a shop shim one because i thought I wasn't getting it right.Looked at some of the wraps that be be bought to be put on starter,wondered how these hold up?Any ideas greatly appreciated,thanks yjmcb

I had a 1986 Chevy Astro van with a 4.3 V6. I used a metallic insulated "cloth" type heat shield which held in place by two stainless steel straps. This worked for me and I never had to change the starter. In the Astro van, the passenger side exhaust manifold IS A TUBE HEADER. It gets super hot in vans but the shield worked. If it didn't, I planned on putting in a metal shield also that went over the starter. As noted, I didn't need it. I can't promise this will work for you, but it did for me. I bought the "kit" from Summit but I don't know what the name was and this was twenty years ago.

Very common prob on chevy V- engines. For years they've made metal heat shields that bolt-on to the starter for about $30, or use header wrap as noted. Summit racing would have all that, and in fact even the GM performance catalog has it.

You might need to wrap your headers, this will reduce the radiated heat significantly. Check on summit racing for their header wrap.
