Thinking about doing a 4g64/4G63 head combo

Another option to consider might be to simply put the 2.4 crank in your 2.0 block. Might help keep your questions minimal as you don't need different cam gears, different t-belt, etc.

Just an alternative to consider as you might have a slightly easier time finding 2.0 blocks.

I would have to find a machine shop to put in oil sqiurters. Not sure if any around here would do that.

I already have a lead on a good 2.0 block. I may just go with that for now. I am not find much for the 2.4's around here.
