(mount hole pads..)

did you do the lifer bores /* ..or where they already done...?


cheaspt.



There are pics of the 10 bolt INDY heads on page 5....

This was a tall deck "673" 48 degree block, so the lifter bores were already machined if that is what you are asking, although I do have capability to put lifter bores in a blank bore block, in fact I just did one for a dirt track racer last month.

I've done the window milling on the bellhousing to alot of blocks, in fact some of the 9" deck Nascar R3 blocks came W/ window mills from MP & were ran in Nascar competition like that. Have never heard anyone question their safety.
