Thanks for the pics, but I think there a bit big? Yes, the stock rods are forged. Aftermarket rods will be stronger than your stock rods.
Time for rod machineing? Depends on if the shop you take it to is busy. If they are not busy,you could drop them off in the morning & they could have them done @ the end of the day.
You would install new rod bolts, then have them machined & resized in that order.
I am not too current on prices for resizing rods, approx $10 a rod? At the most $100 for a set of 6? Most likely less.
If your crank does not need to be turned, just a polish would be good $30 ,turning crank & polish $100 ?
If you chemically strip the block acid dip, you would take out your cam bearings, if they look good & you get the block cleaned w/not so harsh a chemicle they can stay in block & possibly re-use,depends on condition. Need a special tool that can cost $150-$300 to install cam bearings. Again, not too up on pricing. Just thinking off the top of my head.
You can use any of those bearings, I just recommended the KING bearings. I used TRW/Sealed Power w/no problems.
I had told you a good way to prevent detonation is to get one of these: http://www.alkycontrol.com/& one of these: http://www.jandssafeguard.com/
As far as a lump port head & head studs, you just would not use 3 of the long head studs when you switch to the lump ports.
