How many "quarts" of paint are you planing to put on the engine? --- I'm kinda confused here! 1 quart would paint the entire lo-by 2 times or more! To do just do the engine you only need a wee bit of paint!
Also -----" My issue is I am completely new to mixing paint and using a spray gun." ----- then this in your next post!--"I have painted a tractor before without using a hardner and didn’t like the results."!! ---- so which is it?----just askin cause I am confused!
as for paint matching----no 2 cans will be the exact color! You have to have an "eye" for mixing paint!
A frind of mine runs a body shop and I have watched him and his dad mix paint to repaint fenders and doors to match the rest of the cars and it takes YEARS of doing that to get EXACT match.! LOL!

Well my late uncle really is the one who did the previous painting I was there trying to learn but that was 10 years ago and all the painting knowledge died with him. I though for sake of not making a post a mile long and explaining everything I was shorten some things. I did all the prep and priming and he shot the color. Long story short he took it right out of the paint can and into the spray gun. It looked okay right after but there is no toughness to that job whatsoever and I am really wanting to do it right this time if I am going to do it. That is why I am reaching out to those here who might be able to help me
But so far I have gotten ppl saying your not capable of learning or doing it right and not helping me in the slightest so I am getting a little mad and frustrated that no one seams to want to try to be helpful.

As Gary said above, where you get the ironguard (Case-IH dealer or online) should be able to tell you which additives are compatible. We're adamant about safety because we've lost good friends from pulmonary problems that directly trace back to not following PPE recommendations. As far as painting techniques, the instructions with your gun should give you initial settings that you can modify with test sprays in areas that won't show or on plywood, sheet metal, etc.

If you are determined to use hardener, I'm pretty sure Case IH has that as well, one stop shopping! As Bob said, we take these risks very seriously, the minimum requirement for using the hardener is a full body protective suit and a supplied air respirator. You also need a dedicated booth or confined area, away from your main work area and any areas where other people or pets may be, with very good ventilation. You may be mad and frustrated with us but this stuff is not for amateurs.

Thanks for the tip. I was planning on checking on it. Would that need to be done with the head and gasket on and torqued, or just rotate the bottom end around and make sure they pistons don’t protrude past the block height?

My plan was the latter option if that will do it.

they do go past block height with the peak on the piston, the head is recessed for clearance, use clay on the pistons, bolt it up turn it over then pull the head and check the clay for clearance

So I ordered new valve springs from H-bobs and noticed that all 8 valve springs came the same whereas the ones that came out were different between intake and exhaust. Is that a change they made later or a mistake possibly?

Almost certain that I have rotators. They have the ball bearing and springs in them correct? If so I have them on half of them. Don’t remember witch off hand. Thanks!!

Rotators, if present, would be on the exhaust valves. They use different springs than valves without rotators.

Thanks Jim. With that being said would you suggest using my old exhaust springs or contact H-Bobs about getting the correct ones?

I would probably inspect and test the old springs to see if they are okay. I don't know if the specs are different for the rotator springs, but the regular ones have a free length of 1-31/32 and it takes 23# to compress to 1-1/4.
