i have to remove one head to replace a leaky head gasket on my case 400 diesel. i was wondering if there is anything i could do to the heads to improve the engine while i have them off. just thot i'd ask to see if there's a quick and easy 'upgrade' just for the heads. i get my machine work done for free so that's not a concern. thanks for reading

make sure the guides, valves and seats are good condition and that valve protusion is correct, make sure to plane them to remove the groove from the fire ring if there is one worn into the head

If you are going to lift the head,I would take a little more time and check for leakdown on the valves.You already are saving big on the machine work.
