Do the guides for 11/32 stems and have the seats cut for 1.94 intake
Use the affordable elgin stainless valves and you can stay under 600 in cost.
That's real power at a fair price.
@.300 lift the 1.88 are allowing 170 cfm, maybe. Change over and blend it and now its 190cfm @.400 and peaking higher like a 2.02 would.
You can change the cam and make it work better, though that's just a power shift more so than an increase
