What size tap do I need for crank snout bolt hole on a 400sb?
I was pulling my harmonic balancer off to install the new cam. I couldnt find the piece for the tip of my puller. I got it off but I screwed up the first two threads on the crank snout. Now the bolt wont go in that holds the balancer on. 
It doesnt look to bad so I think I could use a tap to clean it up.

The tap worked I can get the bolt in.
I need to run a tap thru the head bolt holes in the block. Do you happen to know what that one is?
