Babbit has been used in diesel engines developing up to 400psi compression pressure.Properly clearanced main bearings with gravity feed systems will stand the 50% increase in compression pressure,especially with modern engine oils shear and load additives.You have to insure the engine is assembled and machined correctly and be sensible in the upgrades.

Ford designed a head for police application in 1931,with a 25% increase in compression pressure,public demand led to it being sold by dealers. Weiand,Winfield and many others offered high compression heads to meet demand.The engine has proven to be robust enough to handle upgrading.

Countless model a owners today use high compression heads without issue,and enjoy the increase in performance.Its is that easy....
