i decided to go with inconel valves, they can handle higher heat ranges than stock valves.
they were pretty pricy, just about 500 for 8 valves.

i do alot of work for my machinist, so i got a discount on the head job,
i paid 300 to get both machined with new guides.

i also replaced my springs and retainers to compensate for the typ4 cam

a whole pile of parts to install on her in the next month...

Are you running a turbo? I have a 7.3 with factory. 093 ATS turbo so they should have inconel valves right? Those valves and Rockers are like brand new jewelry for the idi!!!

Sorry about the double triple post. I meant to say retainers not Rockers lol.

Once they started on them, 2 days. Shop was super behind and it took 10 days before that. My heads were factory turbo so they theoretically had the inconel valves from the get go.

Not bad at all what else did u replace in the heads?

Got some more work done on the engine. Today I got the water pump off, radiator elbow, and drivers side head off. This side was muccchhhhhh cleaner than the passenger side smh.

I'm a newbie, and don't 'get it', I've got a stock NA7.3, does this mean I should keep it stock, and not hunt for a turbo set up, or ? I read a couple posts after this, where the description of the turbo 7.3 seems more 'robust', is that correct, or ? From what I've read turbo'd engines have lower compressions, to accommodate for the boost, so at least in my mind, it would balance out with the higher compressed na engine.....


Btw, threads great, learning a lot, Thanks!

no it doesn't mean that at all.people have been turbocharging the n/a idi's since the early 80's with combined millions of miles without harm caused by 10ish lb boost.
diesels belong turbocharged.hunt away for a turbo kit my friend.hunt away.

This side was muccchhhhhh cleaner than the passenger side smh.

thats the clean side?!!!!

 

[IDIn_It]

Compared to the passenger side it was. The passenger side #1 cylinder had rust all in it. Drivers side didn't. The passage from the thermostat was the culprit.

Since I'm taking apart the motor, do I need to worry about marking the timing on the injector pump at all for reassembly? Or should I go ahead and mark it just in case.....

Might as well mark it.

wouldn't a tight new rebuilt engine have different compression characteristics; which would necessitate starting at the static timing marks?

Are you reusing that pump? If so, you can mark the joint between the gear cover and pump so it goes back the same. Best practice would be to time correctly using a meter when everything is back together.
