I just had my engine rebuilt but did not assemble the block or head myself. I had a shop in Westminster machine and assemble the engine components. They turned everything around in 6 weeks or so. Since it is summer, their work load will be backed up to high heaven.

For reference, Jeff99GS and I (Jeff moreso than I by far) have basically done everything on a DSM that can be done, but we thought it more prudent to allow someone else to put in forged internals. I personally didn't want my first experience rebuilding an engine to be with beefed up components and all of their associated costs (much more to lose with a mistake), and if you are thinking of doing the same thing (built engine), I'd let a shop do it.

If you are going stock again, I'd give it a try, but be extremely meticulous. This kind of work will have no margin for error compared to the bolt on stuff. Just get a FSM and make sure you have all the clearances perfect.

Good luck MD buddy.
