Alter C6 case for converter bolt access

It seems that every time I re-assemble the converter bolts loosen up at least once. I've got a shoe box pan and block hugging headers that make removing the starter and tightening a royal pain.
Has anyone cut the bottom of the case off for access to the converter bolts. I talking about removing a 3" wide by 1" long piece at the very bottom of the case.

I've done exactly that, maybe just a bit deeper - 1 1/4 by about 3 1/2. Without it, first time I dropped a converter nut I had to pull the engine back out to retrieve it. Went back together with the cutout, probably 7 or 8 years ago.

Yes,won't hurt anything.

Mine is probably 3"X6"

Thanks guys I was able to sneak a combination wrench in there but the next time its out I'm going to clearance an opening.

I cut the bottom of the bellhousing open on mine from lower block plate bolt hole to hole 9" wide 4 1/4" deep ,never any ill affects
