Default Head is coming off

So i have a bad water/coolent leak so i have to pull the head off.

https://ls1tech.com/forums/general-m...g-coolant.html

im thinking i should just pull the other head off and replace the both head gaskets since the car has about 140K miles, My question is what else should i replace while im already gonna have the heads off? not trying to do anything crazy i drive the car a lot and trying not to spend lots of cash.

Thanks

Personally, depending on the mileage, i would replace the lifters and trays while your in there.

I would have the heads vacuum tested at a machine shop and have them shave a couple thousands off to make sure they seal to the block decks well. Throw in a new set of ls7 lifters and new trays while the heads are off. Some new Gm MLS gaskets, and I would pull the water pump off and do the gaskets while the coolant is out.

You also could get in to the timing cover and do a ls2 timing chain and oil pump but that's up to you on how far you want to get in to this motor.

comp cams trunion upgrade if it fits your budget. It just upgrades the bearings in your stock rocker arms to make them stronger.
