I've decided to not install hardened valve seats on my NOS cylinder head.
This truck will not be a everyday driver.
My restoration will be a nos restored show truck
and only driven out of the garage onto the trailor
and then off the trailor at shows.
I can't see anymore than a handful of miles per year.
The head will need a very light milling of the mating surface of the head because of a couple of 1 " square areas that has a little more than superficial rust pitting.
I'm going to use this nos head on my original engine block.
The block is code dated:Oct. 5, 1953
This nos head is dated: Oct. 9, 1953
To me it seems like a great match.
Original head is dated: Sept. 25,1953
I looked on the net today.
I do see many shops that offer cylinder head cleaning.
Thermal cleaning seems interesting followed by shot peening.
I don't have the usual baked on crud like used heads.
I just have surface rust.
One possibility is just have is shot peened & pressure washed.
Another option: I could get a bucket of plastic shot and blast it myself in my blast cabinet.
The plastic shot would certainly get rid of the rust.
I must say, I do like the look of a shot peened finish.
Thank You to all that have posted on this cylinder head.
