There's really no sense in going into what their valves and springs are like because they don't have those heads for sale right now they're out of stock. I bought them with valves and springs and retainers and they've been working fine for 2 years.. I practically wasted $95 to have them checked to be told there was nothing wrong with them in the spring rates were super close to what I had already...
Personally I don't like those aluminum rockers whatsoever. They look like the ProForm ones and I ordered those from Summit one time and sent them back the same day...
