More work on my customer's 1911 Model T Ford.
I always use some Permatex copper spray-a-gasket on these copper head gaskets. It helps them seal and lets them come off easy for the next time with minimal prying and scraping. I also put a little whiff of copper RTV around the coolant passages and head bolts to keep coolant in the coolant side and out of bolt holes.
I've found copper gasket quality has gone down over the last few years. The last MGB head gasket I put in heaved coolant out because the fire rings don't crush enough for the rest of the gasket to seal properly.
Head on and torqued with new head bolts. Henry doesn't give a torque value beyond "tight with an X long wrench". 55ft/lbs seems to be the accepted value. Head was torqued to 25, then 45, then 55. Once it heat cycles, I'll torque it again.
Engine is turned nose-down. Transmission is placed on the crankshaft, bolts installed, torqued and safety
wired.
Clutch finger height set. The little bolt has been machined to exactly 13/16" to use as a gauge. You can use a wheel nut too. Once the height is set, the cotter pins are installed.
