I would only use an R block, either R1 if you can find one, or R3. I think there is an R1 on here right now for sale in Tx maybe??
When I do a W5 head, I remove the original seats and replace them because they are prone to moving/falling out! But I think you have good enough parts (minus the cam maybe) to do what you want, with a little more work.
R blocks are fine
That said, i like the X blocks, reason being they are stock up top and will accept anybodies roller lifters, which is a plus,(in the 59 degree and roller cam world) and accesories, etc, are plenty beefy to handle anything a 59 degree head can dish out, and are lighter than an R3
Like any block, they should be sonic checked, mine has plenty of meat for another overbore and its currently at 4.100. Like any Mopar blocks, the thickness varies, hence why they all should be checked.I know guys running them at 4.125 even, and making good power with safe bore thickness.
Same thing here., my x block bore is 4.100 and it can take the 4.125 safetly....i guess..lol
