And the flying flat springy thing.

Yeah, pulling out that steering column is a bite.  Mostly due to the knuckle thing that always seems to be tighter than it needs to be.

looks good, did you do anything in the intake bowls/seat area? it looks like you opened up your exhaust more than me. i wish i had done it more like yours, but i was trying to keep it simple.

how much time did you get into it?

i believe there is a nice kit for the steering column bearing these days.

in the past or just for a temporary fix many just push it back into place and then use a hose clamp to hold it there.

  Is the pickup AC or not?
 There is an easy way to change the heater core in an AC car.

Brief update:

I have not had any further work done on the head due to my friend unfortunately having a stroke. At this time we don't know if he will be alright or not, so that just plain sucks.

In the mean time I've started cleaning the block out of buildup and replacing the heater core. One other thing I have to tackle is the bearing on the steering shaft inside the car. That seems like a fun task!

Exhaust port on head gasket side before:


Exhaust port on head gasket side after:


Overall first porting on headgasket side:


Exhaust ports before and after on manifold side:


Other two:


One left:


Final product:


I ended up smoothing out the exhaust ports to keep airflow as laminar as I could. While keeping the intake ports dimpled in order to promote turbulence for more efficient AF mixture sooner.

My concern is if you surface it flat, the cam will rock when it's installed.
It will be pushing down very hard on the center journals as it runs.

I used the glass plate and very fine, like 400 grit paper with oil, and got my head to come into tolerance.  So I think as long as you are careful with the precups on a machine you would be OK.  True or Not True?

 You test drove it and that fixed it?
