I had a machine shop do my current block because they assembled it. Sharp edges and points in the cast iron create weak spots, be sure to round off all modified surfaces. Good luck.

On a factory 5.0 block you won't need to with a 331 kit. Seems like a DSS block you will.

About all 347 kits will.

It takes about 30 minutes to do it. Of course if you have to buy the bits to do it, its probably a wash letting the shop do it.
