Hey guys, quick question for you. Currently I'm running 66 2v 289 heads on my bracket car, I have a set of 75ish 351w heads from a t-bird. My major question is what are the chamber cc's for each and what are the valve sizes, also will I need to change anything to bolt them on my 306? It's a 68 block by the way. Thanks guys.
