made some more aluminum dust...

Got back into porting these '76 930 cylinder heads today.
I enlarged and smoothed the 32mm intake ports to 40mm to match some 40mm aluminum CIS injector blocks I have.
The valve guides are new and the valves and seats freshly ground so I have masking tape on the valve seats and pieces of rubber hose on the valve guides to protect them while doing this.

It's only 90 degrees and humid as a swamp in the shade here so a blower fan helps to stay sorta sane...

They aren't finished yet but they're getting close so I stopped and snapped some pics.
The first pics is from a couple weeks ago when I started hogging them out to around 39mm with a carbide burr.
