Valve covers removed. This will expose the rocker arms, valve springs, push rods, and the other two head bolts.
The engine is at the machine shop as off 11-21-00. It will be bored out .060" and will have new Wisco pistons and billet aluminum rods. I will modify the valves and rocker arms to handle 6000 RPM. More pictures will be posted soon.
Want to do this to your engine? It's really easy and a Briggs repair manual will walk you through it if you are unsure. I can help with anything on a Briggs engine.
Torque specs will be posted on this site. The only special tool you need is a torque wrench (~$20). It is very important that heads, side plate, rods, and other parts are torqued to specs.
