If you don't put better rods in it you won't be able to rev it to where it can make some power,The stock rod are probably good  for about 4500 RPM and you will need to run it almost twice that high to get some power out of it,more compression makes more power too so you should mill the heads,then you will need a better camshaft too.The 23 HP heads are some of the best flowing but they need porting  and better valves springs and retainers.The stock rocker arms are not much good for racing either

We race with a set of rules that states anything over governed speed needs a Billet Flywheel.
The oppy in a finicky animal, you better do some oil mods {found in search} if you want to go over
the governed speed.

Thanks

The problem is the tower is to high for the late model heads. EC will make [2] two towers for the different heads. For now just measure the tower and the rocker stud towers and machine the rocker arm tower off, mine needed .206 " milled off.

The rockers are flat across and hit the valve stem real close to the center.

The stupid slide show loads backwards, Duh

Ok because looking no at these pictures he didnít factor his guide plate into his measurements for cutting the mount down.  Seems like after he adds the guide plate now the other 2 mounting bolts wonít be flush with the head
