Now the block is almost put together, I chased the threads on the head bolts and used a tap to clean off threads on block, now do I take a bottle of brake cleaner and spray the holes with it while the block is upside down, then use air for the rest to get all the junk out?

 

yup exactly what you said, air is a must to get all the **** out of there.

 

make sure to put some assembaly lube on the head bolts when you put them back in. I just dipped mine in some clean motor oil.

 

Cool thanks!

 

i take an old headbolt and cut 2 slits with a dremel from top to bottom of treads and the dirt gets stuck in the slits when u spin it..
