Inliners International Forums General Discussion Engines 292 with a possible 194 head??? 3788380

The lumps will help, even with a stock cam.

The lumps will not help a head with stock size valves.

The valves in your head are 1.94, stock is 1.72.
Notice the dyno chart at bottom of this link. It shows a comparison of a stock head/ cam to a built head with stock cam.
