TFS head quisetion
I was planning on buying these Trick Flow Specialtie heads, and was going to run it with a CC503 with 1.6 rollers. I was wondering if i have to switch out the valve spring that will come with it? http://store.summitracing.com/partde...0&autoview=sku

smaller! I think 58cc is stock and most mill them down to 52-54cc can't remember to get the compression in the 11's. This is based off of stock pistons as well. Changing piston's can alter compression also, depending on what you get. as well as head gasket thickness...
