Re: Johns 66
A set of 461/462 heads would be nice if you can find a set. The 1.94/1.5 valves will be just fine. No need for 2.02/1.6's. The factory 300 hp 327 cam is quite mild and there are much better cam profiles available these days. When looking at aftermarket cams, keep in mind that any given operating ranges are typically based on a 350 cu in engine. Using a given cam in a 327 will move the power band up a few hundred rpm's as compared to that same cam in a 350.
