Looked like you did good selecting the ebay valves. The ones I posted were the longer ra 4 valves. With the bigger cams we use those with a taller spring and the longer Melling 11/32 ra 4 pushrods with a 995 compcams spring. If your pulling the heads off and putting new valve in and want a cheap upgrade on the push rods from the stock 5/16” push rods that works great. That combo with the melling ra4 1.65s is a cheap upgrade.
With stock valve length I don’t know of a better spring than the Crower 68404’s.
Quality wise the summit cam is of good quality, just an older profile. That 231/239 Lunati you looked at is an old Ultradyne grind that goes back to the early 1980s. It was Ultradynes claim to fame. Great cam.
Save your money on the cam and get some nice lifters=hy lift Johnson
