When u Shave the head do u have to add shims or what??? i have heard after a point u have to add shims. I would like to upp the Compression to 9.9-10.1:1.

I know the E-88 has the smaller valves what would it cost to replace with the larger valves?? How much machine work would that take to do that kind of work??
Will I get that extra HP from the Larger Valves is it worth what it would cost?

What should i spend that money on with my head to get the Extra HP besides the valves.

Add shims if you shave head over .015

Goodson sells the shims for $9.99 a pack. You will need five packs if you shave your head .075. Also, you will need to use two valve cover gaskets when shaving head over .040 or the cam towers will hit the cover. Sorry, but I don't know what the machine shop would charge to install the larger seats. Later,norm
