Stroker Crank effect on port timing?

[TK Boxer]

I remember before the BilletBoard went down you had a post with great info about your new stroker cranks. It said the weight of stock RC and LH cranks and the weight of your new cranks. Could you re post this info?

Also if I remember correctly there was some info on how the crank effects port timing, Could someone elaborate on this subject? How is top end mid and bottom effected?
