I removed the engine from the Mach the other day. I have a few days off of work, so on Monday I will do a mini CSI investigation on the engine. The drivers side head was seeping a little coolant out. I think I will have the heads plained and have the intake machined so it actually fits properly. I will also retire my cheepo torque wrench and buy a proper one! I had planned on putting the heads on a fresh short block, in hind site, I should have stuck to my plan. The old abused short block was fun while it lasted though! It will be interesting to see if the Mach makes it on the road next summer. My budget is slim and I learned my lesson on short-cuts this summer
