FWIW, we usually find that after a valve job seats the valves in a little further, and swapping in a higher lift cam that uses a smaller base circle the stock pushrods are closer to the correct length with some taken off the heads.
I have some .005” over 400 domes on the shelf. The last set of 400 pistons I bought were IC890 Icons. They gain some compression over a stock 2262 speed pro or a cast piston, don’t quite get the SCR as high as a dome though, and the min size is probably .030” over on the ic890s. For the money they are nice pistons.
Barnett performance might be a good shop to check out for cams, I think they are in Alabama. I have bought parts from them that they stocked that were hard to find otherwise. Would be worth looking into, I would rather run this cam than a 2800 summit.
