I forgot to mention, the only problem I had with the Ashley manifold was the paint they apply to it is not a heat resistant coating and just burned off in minutes. Not sure why they bother applying anything at all as when half the paint is burned off it looks terrible. It also smoked like hell!
Anyway, after deliberating about what to do, I bit the bullet and sent it off to Zircotec to get it fully ceramic coated. I pick it up on Monday and then its straight back onto the car. Only problem was the ceramic coating cost almost as much as the manifold itself but I think with the heat transfer/reduction it will be worth it and will be better than even a stainless manifold.
