You may have some dyno pulls omitted from your copy of data, but stock head(1.72" valve) with lumps and stock cam and Clifford intake. Then same exact head with stock 1.72" valves and lumps, Clifford intake with Cam #1 installed = 31 HP increase!
Ummm, I thought that's what I said. All the combos with stock cam are about the same. But the cam makes the difference, even with the stock valves. But more valve is even better.
