Teflon "white" seals are often the cause of excessive oil use in SBC. Usually the installer trys to install them cold and damages the sealing surfaces..
If you use the "Blue" Fel-Pro type positive intake seal. You will get better oil controll.
I tend to use a good "umbrella" seal on the exhaust side. Remember there is negative pressure on intake and positive pressure on exhaust. The exhaust can use a little more oil flow and won't run down stems/guide while running.
As for bronze liners. PROPERLY INSTALLED they are the best economical repair. Will last three times as long as iron and can be run tighter clearances.
