Just stay with the standard size CJ valves, 2.09/1.66 because this will not shroud the valves. With the PI intake, 10 to 1 compression and a nice hydraulic roller and if the heads are prepared correctly you should make 500 to 525 no problem. Let me know if I can help you with a camshaft design and lifters. You will also need special lenght pushrods with the hydraulic roller set up. we have all of this in stock. Thanks, Keith Craft
