So here is the latest. The engine runs great but it has a noise from the valve train. I thought I could salvage the old head but when it overheated I must have bent or damaged something in the top end. Looks like a new head is in the works after all. Looking to get the 0331 replacement head with the built up critical areas and also remachined to accept the larger gm intake and exhaust. Flow rating appear good so it should be a plus. Going to check oil pressure with a mechanical guage since my "classic" came with an idiot light. (Cluster replacement on my list). Now that we are semi settled in, time to get back after it.

 

So it looks like its about time to start my year down process again. I should be good at this by now. More to come.

 

 

The new cylinder head is on order. Now to wait.

 

Where did you end up getting your cylinder head? Is it the TUPY casting?
Sounds like it is going to run awesome when you get done!

 

I ordered it from Odessa cylinder heads. New casting with reinforced weak spots. Its supposed to be stronger in all the right places.

 

New GMB performance water pump on the way. This project is taking forever...

 

When are you planning to have this done? I just read the entire thread and now I'm curious. lol

 

Well the project has been paused a couple of times because of moving but I am back home in Vegas and of all goes as planned...before jan 1.

 

So the new water pump is assembled and ready for installation but I'm going to wait until I put the cylinder head on. Waiting on the new severe duty gasket on going to install. Ordered a new high-speed multi-blade electric fan to replace the stock AC condenser fan. Hopefully all the parts will be here by the end of the week so I can start reassembly on Saturday

 

All parts are in. Time to reassemble. Now lets just hope I can remember how it all goes back together.

 

You can do it. Just like riding a bike. Even if it doesn't come easy, there is lot's knowledge and help on this forum. P.S. Merry Christmas and Happy New Year!

 

I just went through something similar to what you're are going through. Here my thread. Maybe you can find some useful information there. https://www.cherokeeforum.com/f2/90-...y-91-a-181505/

 

The reassembly begins. The Felpro Severe Duty gasket.
