302 head progress and questions

If you’re really using a drill....... the pessimist in me thinks you’re only going to get so far with that.

How about a pic of what you’re using, and of the burs.

IMO........ most people trying their hand at porting for the first time are over zealous, and bite off too much.
They often discover after they’re about 1/2 way through the job that it’s not glamorous work.
Especially if you’re working with tools not really designed for the task at hand.

I got access to some new carbide bits and a Milwaukee with like 4 battery packs. As it slows down I swap out and charge the old pack. Don’t have access to a large enough air compressor. Agreed, it definitely isn’t glamorous work, but I did expect to be further along after the time I had invested. Can take pics when I get back to the shop maybe this weekend.
