I went ahead Saturday started replacing the intake on my 1967 F100 .Got everything off the intake and made a bracket mounted where the carburetor was. I lifted out boy that thing is heavy I want do that again. The rest of Saturday I clean everything up really good. Sunday I got started digging out my cherry picker got it fitted close to the arm wipe all mating surfaces down with brake cleaner and 90% alcohol. Earlier I put my cork gasket on the block let it set up for couple hours. Well I install the gaskets on the head use rtv on both sides
of the gaskets and lift the I intake up and carefully guide the by pass hose on the water pump and sat it down on the engine. I like to never get the bolts started because the by pass hose wouldn't let me move it like I wanted to hitting in with a dead blow hammer and getting up in the engine bay pushing on the intake with my foot about 30 minutes fighting with it .I got all the bolts in I stab the distributor in after little more adjustments . Well I had a bright Idea take the distributor out so it wouldn't be in the way when torqued down intake. When I stab my distributor in I had a hard time but it fell in place . Button everything thing up about 9 hours on Sunday. Today after work came home change the oil with zinc additive and put antifreeze back in .It started up like it was never touched. I left the valve covers off let it run burp the system but I have still have little beads i the oil that is clear but on the passenger side like before little bit of green in the valley . I walked a form it went in and had supper went back out and torque from 30 to 35 ft pounds I didn't started it up my guess the passenger side head has a cracked in it . Ps I used the standard fel pro gasket set

I found the issue crack just below the valve spring on the passenger side mid way to the back. I run it till it got up to temperature shut it off and wiped where the oil runs and watched the green antifreeze seeps took a light and seen a very small hair line crack I two places . Well it's time to make some decisions replace the head or take the engine out and rebuild it . It run really good does not run hot cranks right up . I fixed the oil leak with the intake everything thing else is dry on the bottom end . I'll be busy this fall .
