The parts book shows 2 different length head bolts but some of them have a stud attached to them and I think those are the longer ones. If the car has factory A/C, you'll have 4 long bolts. If not, you'll have 3.
 
BTW, the number of long and short head bolts varies from year to year. 67 always has 2 long bolts, the above is true for 68, 69, and 72. 70 and 71 always have 4 long bolts.

All good advice here. I vaguely recall the "right front" head bolt, that penetrates into the water jacket, is *slightly* shorter then the others. I had a terrfying scare once when I started the engine after a routine head job and got a horrible noise -- simply the tip of that bolt fluttering against the water pump blades. No harm done.

This was a 1970 232, and this happened in 2004? So who knows, too-thin a washer under the headbolt? One oddball bolt? Thinner gasket? Slightly oversize water pump blade?

I swapped the bolt, retorqued, no further problems. When cars get this old many variables creep in not factory-installed.

There is for sure a head bolt that needs a non-hardening sealant on it (The TSM says to use Permatex #2). I think it's the one in the front of the head on the manifold side. If you shine a flastlight in the waterpump cavity, you'll be able to see which on it is. The only other place where a dab of sealant is needed is on the rear main seal. I also use Permatex #2 on the water outlet gasket to make up for slightly warped outlets.
 
I don't recall the TSM saying to use any lubricant on the bolts but I don't have one in front of me.
 
As far as the pushrods go, you should be okay as long as they are straight. I rebuilt an engine that was run for a while with next to no oil pressure and while the rocker assembly and valve guides were badly worn, the pushrods were okay.

No loc-tite required anywhere.

Some others might have suggestions on lubing the bolt threads. 

One of the front bolt holes may be drilled into the water pump cavity and may need sealant.

What about loc-tite on bolts?

If you still have noisy valves you may have the same problems that I have. Your rocker shaft and some of the rockers may be worn. On my engine changing lifters did not solve the problem. 

I found a replacement assembly but haven't had a chance to try it yet.

Galvin's in California and Kanter's (NY?) sell replacement parts.




Vinny,
Thanks for the offer, but we're looking to assemble this weekend. I was looking for the length, to check the existing ones for wear.

Anyone know the correct pushrod length for a 68 232?

Head is back from the valve job, and the shop also suggested the original bolts were good to re-use. They noted if they don't torque, they'll need to be replaced.
I would think stuff made in the '60's is better than stuff made today...
