Hmm 91 is premo and 89 and 87 are mid then we have 85 for cheap but it aint that mixed E85 garbage.
Do you know whats so great about the Aus heads?
I hear allot noise about them online but never really what makes them so much better then other brands?
thanks JB!Aussie heads are just stock iron heads from a 302c from austrilia. They are just 2v heads with closed chambers. The closed chambers, with the correct pistons (.035-.055" of clearence), will create quench(turbulence actually) which does a better job atomizing the fuel and will let you run higher dynamic compression ratio without needing a better grade fuel, and still making more power. The stock 2 barrel cleveland heads are prone to detonation and that IMO is there biggest downfall.
