I used ARP bolts but would think you could run stock bolts. Ed at Trick Flow would be able to answer that for you I'm sure.
Stock 302 bottom end. I didn't dyno but it's been proven these heads flow circles around a fully ported set of 186 iron heads. The intake runners alone are way bigger than stock, and the 60cc chambers are a modern design with excellent port design and flow. There is room for someone who knows what they are doing to get a bit more out of them but these are supposed to be just as good as Trick Flows fast as cast 195cc heads in terms of numbers. That should be an easy 50hp gain in that area.
