Twisted Steel Performance
Anything worth doing is worth overdoing.
Spent some time on a CNC mill today, after installing big exhaust valves something had to be done to unshroud the valve because most all of the stock edge was gone and the valve sat in a closed hole... see the last pic..
This is my version of unshrouding, I think this will increase flow even more than the stock angle cut...
Now a little finish work on the ports, some coatings, different springs and these will be ready...
