im not saying a BG is a miracle worker but it does help stabilize the cylinders. and ive seen sleeves split that didnt have one. maybe it wouldve split with the BG but im not risking my engine for a 150 dollar part.

The bone stock engine i put the hks headgasket on with 15psi didnt have one in it but i didnt car bc i had a built bottom end already assembled and 2 more spare shortblocks.

the weak link of the b16 and boost with factory internals are the ringlands anyway. but im just throwing some options out there.
