Does coolant pour out when you pull the heads off the 60 block?

When u disconnect the heater hoses coolant will pour out and some will still be left when u unbolt the heads and it will fall out when u pull the heads off...just get some rags and compressed air to get it out the cylinder after u have the heads off

Yea there will be coolant still in the heads up against the head gasket. So once the gasket unseals from the head, it will **** coolant. Like mentioned above, just soak up the coolant with towels and then blow the cylinders out with air.

Thanks for the info. Wasn't able to get to it tonight after work. Had to straighten up garage.

Make absolutely certain you brake cleaner (preferably non-chlorinated) the head bolt holes then use compressed air with a small hose or long nozzle to blow all liquid out of the bottoms. If you happen to screw a bolt down on top of liquid, you'll probably shatter the block.

Are GM MLS head gaskets reusable? Thanks suburbazine that's a good tip.

Suburbazine

No, they are not considered reusable since they have one-time-crush sections that allow them to seal perfectly when the head is torqued down. I wouldn't even use one that was dropped on the ground or had the box crushed.

I reused some LS9 gaskets before, worked fine...not that I would recommend that.

Yeah I'll just buy a new set of head gaskets, cheap insurance.
