Twin-plugging and other modification to the 2.0L race engine
caused me to take this low hour (18) down this far.
My Piston to valve clearance is too tight (due to going from a DC 60 to a DC80 Cam) so the pistons are at Ollies getting a little machine work done.
Here is a shot of the boattailing, knife-edging and piston skirts moon cut.
I know their are alot of arguments whether or not this increases HP. It sure cant hurt.
