You can't detect differences in cylinder heads with the naked eye, it's the volume of the combustion chamber which you must measure with a liquid and a graduated vial in cubic centimeters.

No such thing as a 4bbl manifold, doubt it would make an appreciable difference on a small motor. Aftermarket fuel injection can be adapted, quite costly and will only affect "driveability" such as warm up and carb icing. If you want better performance consider a Packard 4M2500 engine from a PT boat, 2500 cubic inches and 1250 horsepower, at least your car will be "all Packard".

Yes later Packard straight 8's had hydraulic lifters but those engines were designed for those lifters. Just like V8's had overhead valves you can't take them and plop them into your motor.

Good luck with your motor, at each step ask the forum for advice to be sure you're going down the right path. We're here for you and your grandfather
