Leaking head gaskets

I heard it's common for IDI's to leak at the rear of the heads. Has anybody had this happen to their IDI? How long did you drive it like that? Is there a way to prevent it from happening again after replacing the gaskets, like head studs or upgraded gaskets? My truck is currently, clearly leaking at the rear heads. I have to add some oil/coolant about every 1,000 miles but it drives great. Will it be fine as long as the two (oil/coolant) don't mix?

I'm guessing it's not a good idea to turn the pump up while the heads are leaking?

When I replace the head gaskets, I also plan on adding ARP head studs, Auto Meter boost/egt gauges, turning up the pump, and replacing all the glow plugs with new motorcrafts. The truck just hit 180k and my goal is 300k. Is there anything else I should replace while everything is apart? Is there anything I can mod for better performance while everything is apart(smoothing down anything on the intake/exhaust manifolds, or on the heads, etc.)?

Just watch you EGT's when you turn the pump up, you could have some head work done if you really wanted to. Check the glow plug relay and any other leaks. Make sure you use the correct coolant also.
As performance goes, all thats really left is a custom cold air intake and/or propane
