I figured with IV heads and my current flat tops I'd end up around 11.5:1 or so, price I'd have to pay to play.
For the tracks I want to run in Vintage racing over the next few years I'll have to switch sanctions to run those. Basically, bucket list racing.
Vintage sanctions can be hard to jump one to the other unless your car is built to a nationally recognized class. An iron headed dual plane gets me within their rules.
