well it comes in a kit, a bunch of rounded off sanders..if that makes any sense...im assuming u have an air compressor so just hook on one of the cone shaped ones from the kit and u'll be able to get around the valve guides...i just did my this last weekend...my head will be out of the machine shop fri...so when i get it back i can show what it looks like...although my head will be semi put back together, just the valves and valve springs

 

bowl, short side radii, and the transition from bowl/shortside to the first cut (valvejob) etc.. basically the last 1/2" bfor the flow enters the chamber,
on the intake side (like u pictured)

 

you can't get around the guide without mowing it down...you don't have to take it to the roof though, you can just blend it to the top of the guide boss and shape the guide boss.

 

here's basic food for head porting

btw ur polishing looks decent

 

do this to help get air around the valve guides. looks good, keep up the good work. dont be so easy on it
