Re: question about aussie 2V heads
I had 302 closed chamber (Aussie) heads on my 351C. Depending on what pistons you have (dished, flat top), compression could definitely go over 11:1 - mine was so high I couldn't run it on pump gas. I was going out to the aerodrome every few months and (illegally) buying 90gal of aviation gasoline.
Then I blew both headgaskets almost simultaneously - so changed to standard 351 open chamber 2V's.
But it had some mean compression with those 302 heads on...
