[QUOTE="Rich Rohrich, post: 124749, member: 16241"] The cylinder head can be made a little better but nothing earth shattering. The guys who are charging $700 plus for headwork are to put it bluntly, jerking people over. I believe there is a lot to be had by using adjustable cam sprockets like the Falicon pieces and different base cam timing. I have some ideas on what should be done but so far I haven't seen anyone that is producing a cam that fits my needs. Even with a different grind, without a lot of dyno time you are rolling the dice. This engine responds incredibly well to an increase in displacement, an increase in compression, tightening the squish clearance, and retarding the intake cam timing. I'm afraid if you go the porting route alone you'll be disappointed. [/QUOTE]
