I havent fully decided yet actually. Most decent shops wont touch it for less than $500 for a basic port and polish, and I dont think I can justify spending that on minimal gains since im using a blower.

For simplicity sake, I like the IWIS heavy duty timing chains. By all means there is nothing wrong with a good double roller chain, but attention will need to be paid to clearances. Besides ease of fitment with the good single roller, it also makes using a factory chain damper a breeze as well; of course I noticed in the great picture of the front of your new motor it is not factory drilled for the damper though. I don’t know if they still do it or not, much less the aftermarket, but GM used to include a template for drilling and tapping the block when you purchased the damper from them.
I liked your little spreadsheet by the way, cool!

Yea im pretty certain a single roller would be fine for me, but then I go back to if I ever want to upgrade its 10x easier now when its on a stand than when the engine is installed.
