Head Gasket Question

:oops:
for 11.00 t0 1, you should be running an alum. head., that`s too high for a cast head, not that it won`t work, it just won`t do it w/o running higher octane gas. you can typically run a point higher w/ alum.-just sayin---bob


Slant sixes can run 11.0:1 with the right cam all day long. Small bore, long stroke, poor breathing = low VE = low chamber filling = less pinging.
