So you think a thinner head gasket will do the trick? I've read where people say to call Comp Cams 15-20 times and go with whichever they recommend the most, since you won't get the same recommendation.
If I may pry, what's stopping you from getting a custom? I worked with Jay and got what I wanted, but I'm sure Ed can do the same for you if you don't want to deal with Jay, for whatever reason. Those guys won't only sell you a cam but tell you what you need to make it all work together and still help you out after the purchase. Comp cams will not do that.
Just a heads up.
