td42 light engine mods

You can get a new intake plenum, for better more equal flow to all cylinders,
I have one from A.R.E. in brisbane, I also have a tri step valve grind, due to time constraints I didnt get the head ported, which is on the cards just not a priority, this time while the head is I will get oversize valves aswell.

With all this research Im doing ben-e porting the head is unjustified however oversized valves will net you a good increase. The TD42 head is pretty sweet straigh out of the box.
