There were several design changes by Bob and Frank after they bought the rights to casting up the All Pontiac blocks vs the IA (Indian Adventures) blocks.

I don't know what this means, but the Dick Duclow IA1 blocks were not cast as exact GM replacements. They were based off GM blueprints with improvements for strength. Then Dick sold off the rights to All Pontiac who made further improvements. I spoke to Dick about this at his house in Massachusetts.
