The motor is double sealed. .
I KNOW GM seal bolts can be defeated. So do many others in field. As for track-seals; where there's a will ( $ ) there's usually a way.

Re: SBC Cam Retainer Bolts/Cam Sprocket

FWIW
have a GM service manual for L31.
Cam retainer bolt Install Torque quoted 12 Nm or 106 Ib in with no thread locker.

Doesn't take much force so trim heads as CGT did; perhaps clean threads & a dab of blue locker

Re: Chevy Goodwrench Crate Motor Info...

Regional 2bbl restricted class allows flattops (but not above deck) & requires unported OE iron heads (but chamber no less than 70cc). SFT Max .480" VL. So everyone runs earlier heavier production 76cc heads milled to 70cc. Quench Gasketed just to point where piston barely kisses head when running. ...

Re: 383 build for heavy truck and towing

Build the L31. North American-made replacement lifters very reasonable. Don't skimp on pistons; OE L31 are well made & have very good metric ringpack NPR offers an unusual replacement option for L31; they offer +10 over piston as well as +20, +30, +40.

Re: motor mounts

Throttle Cables are not immune; especially transverse mounted motors w/bad mounts aka dog bone mount.

Let that 400-500 lb motor slam itself up against the limit of throttle cable & it'll pull that throttle blade WFO
