Never had any heat related starting issues ever, I was using a stock starter.

I've never had any heat related issues either using the RA manifolds. I've used the por15 as well and even though it doesn't necessarily have heat barrier properties it is a very nice product that is cheap and easy to apply and does last what seems like forever. I've had it on my RA manifolds for several years now, daily driven, and they still look like new.
