452 heads on a 1965 Wedge ?

I can do that for you... but you would be better off learning to do it yourself.
I always recommend the calculators at Wallace racing, they work easily and well for me... and he has about a hundred of em.
Trouble is, for ACCURATE results, ACCURATE measurements are required.
(And I would assume the 452s at about 88-90 cc, and I would assume the 426W factory rating for c.r. is optimistic, like most Mopar c.ratios)
