Most likely not enough to justify the pain in the ass job it is to keep a leak-free spacer between the head and the intake manifold.

I personally planned on running one once I get my manifold. I've just never heard anyone say that they are a complete waste. I figure they can't hurt. But I haven't researched the topic to death, so all I was asking is if you have some good info about why they are such a waste of time, I'd be interested in reading it. I don't think I'll have a problem keeping it leak free. A gasket and some copper spray should work fine, plus the fact that I'm going to have the flange milled before I put it on the car to ensure it's flat. I've definately touched my head after some driving, and it is definately hot. No matter how short of a time the air is in there, I'd think a little bit of that heat would effect the air temp in there. So if you have some good info on it, please share. I'm going to search about it for a little bit myself though now, because now I'm curious as to what could really be wrong with using one.
