As soon as I posted that I realized it wasn't what you were asking about. That is the tool I use to pop in the push rods. I don't think I used an specific tool to remove the springs. As I recall it was a bit ugly using a few different tools for leverage. I did it with the heads still installed and using compressed air to keep the valves in place.

These work in a pinch and also for removing the spring with the head on the engine. Many similar looking versions out there but not all work as well as this one. It is the same one that I have in my tool cabinet.

Hey, I figured it out. Saw another reply where someone took a large socket and hammer and gently "smacked" the top of the springs. That loosened the "keepers". C-clamp does work. Duh!
Onward and upward!!!!

Ok, got the heads off, cleaned and they look very nice for sitting 30 years. Question: has anyone ported/polished the heads/intake manifold? Is this worth the time/$$$ given the restrictive flow of the 345?

In the simplest of terms, it's a waste of money.

The IH sv can be brought up in power, but not like you would expect (for example) from a small block Chevy.

A simple porting/polish won't not do anything.

I appreciate the response. Helps save $$$. Just needed to confirm before I put this thing back together. On another note: the umbrella seals vs. The standard ones? Any thoughts?

Is the disassembly of the rocker being advised for all engines that have been sitting for a long time or just ones that are knocking?

Yes, low rev engines.

That's a tough one. If the truck has been sitting you definitely want to spin the oil pump with a drill motor. Ideally you verify that oil is flowing up to the rockers. The only way to do that is to remove the valve covers. Ideally you have a set of half covers to keep oil from running all over the place.

Rocker noise is likely to be from lifters so re assembling rocker arms wont fix them. If you remove lifters and put them back remember that everything has to go back where it was!

If you are going that route post here at IHPA and get opinions. There are plenty of people here that know more than me.

Have fun
