Hey Todlich, I bought my heads direct from Engine Quest in Vegas. I can see the valve lift you are looking to use is a little higher than mine. I have .512. Mine was pushing it, the retainers get close to the seals. So you may need to talk to them and see what the options are. Maybe taller valves, or cut down the spring pocket a little lower. Might be just as well to buy the heads bare and piece them together yourself. I bought them loaded and ended up only using the valves, so it was a bit of a waste of money in the long run. My heads only had the standard size valves also, but they seem to work well. They really seem to like flowing up to about 6300 at least.

My pistons are basic .030 over cast replacement ones. They are about .060 in the hole. The best math I can figure puts me around 9.3:1, which I perfect for where wanna be right now.
