I;m running long tube headers on my 347 in a 62 F;lane. I didn't order them coated mainly because I knew we had to "re-arrange" a couple of tubes, 1- to clear steering rack, 2- to clear bellhousing, so I sprayed em with Eastwoods Hi-heat header paint. Other than protection from the elements I doubt the paint helps in lowering underhood temps, to any degree.,
Which brings me to my question - Does header wrap really help reduce underhood heat, enough to warrant using it?
My son used wrap on his Subaru headers, which, by the way, were ungodly expensive (Syms) & then sprayed the wrap with this - DEI- Hi-temp silicone coating, which supposedly seals & protects the wrap. The spray certainly dried into a tough, hard coating.
I ask because I think underhood heat is a major factor in hot start issues, if I wait 1/2 hr. she turns over & starts, no problem.
thanks
