I will post up pics this week, but I am building up my 3L block for the Contour this week/next weekend. This past weekend I finished one head and am to the point of cutting in the injector port and filling the center injector port. I documented the entire process, but have yet to download the images from my camera and post them in my writeup thread. When I do, I will cross reference the porting pictures here.
I'm using a product called "QuickSteel" to fill my center injector port. Within 15 minutes of setting up, I can smack it pretty good with a ballpeen hammer and she stays put. Within 24 hours, the stuff is fully cured and can be ported/sanded. Best part is it smells a little like bubble gum, so porting it actually makes the garage smell nice
