Does anyone have experience with Summit brand cylinder heads? Specifically I am looking at a set of cast iron heads with 72cc combustion chambers, 2.02 intake/1.60 exhaust valves, 1.25" valve springs good to .520 lift and 165cc runners. Summit part number SUM-152123. The valves in these are bigger than the vortecs with only 5cc less on the intake runners. They will be going on a built & bored 327.
I have read a few times that the Summit brand parts are often good parts that Summit has just put their name on. I don't know who makes these, but the price is good and the flow SHOULD be what I'm looking for. Any comments, recommendations, experience?
