Yes, the 2v are prone to detonation, but don't confuse that with them not being able to work. A lot of people disregard them, and i can't say it's totally without reason, but I can assure you the heads are more capable than some people think. We run a dirt track car with a 351c, where they outlawed the aussie heads about 4 years ago, that left us with plain old 2v heads... The last one we had on the dyno made 418hp, 424tq, through a stock 2v intake, stock 2v heads, 500 cfm 2bbl, all unported. We're now around 13.5:1 compression (using flat tops btw), and have not had any failures in about 2 years now. These things require VERY little timing, and with the appropriate fuel and cam, can be made to run well.
