2.0 Engine Rebuild Advice Options

[VWTortuga336]

I'm working on stripping down my 2.0L out of my '74. I've done a top end rebuild on my '71 Type 1 engine, but am new to Type IVs and bottom end rebuilds. So, I'm looking for some advice.

So far, from what I can tell the heads on my engine look like they are still in good, re-usable condition, but the engine is seized and the cylinders are badly rusted to the pistons. At this point, would I be better off just using the BFH method to destroy the 94mm cylinders that installed now and go with 96mm's, or is there any hope in saving these? (I'm thinking there isn't) Also, there was water in the case, so what does that typically mean for internal component replacements - cam, crank, bearings, etc?

Just in the planning phase now and trying to collect as much info as possible.

I was finally able to move the crank and begin removing the pistons. I'm to the point now where I have been able to actually split the case and begin removing internals. I have a few questions:

1. I'm going to be running carbs on this engine and want to make sure I have the right cam to match. The cam that's installed looks to be in good shape, but I want to make sure it's correct. Where is the cam stamped to identify it?

2. Since there's a good chance my case is toast, due to the broken boss above the oil pickup, I'm going to attempt to reattach the broken piece, build it up, fill in the threads with JB Weld and re-tap it. I know this might not be the best, or most robust solution, but given the fact that cracking and/or breaking these on Type IV engines is very common, I'm thinking this might not be all that bad. Anyone ever tried this? Am I totally crazy for thinking this might work (IMG:style_emoticons/default/smoke.gif) ? (Pictures below)

3. The crank has lots of surface rust, but from what I can tell (very new to Type IV, untrained eyes here) seems to be in decent shape. What should I look for to determine if it's salvageable?
