Ive heard a lot of people say that the head gaskets with the integral firre ring are better, what makes the ones with the separate ring worse than them? Also, does anyone know where to get the integral style gaskets? I can only find the ones with the separate rings, and they're always part of a kit which just has everything I need.

I see the new gaskets have some different holes than my old ones. The ones that came off my truck look like this head-gasket-m35a2.jpg
Whereas the new ones look like this

What's with the different shaped lifter slots? Is it just part of the updated design? Or do I need to buy the older style multi piece gaskets

Sorry to hijack but it may fit the thread. Seen on previous posts guys recommendations of what to look at when the pan is down. Can't seem to find those posts now. Took mine down for cleaning, painting, gasket change. My LDT looks to have 12pt bolts already installed. Looks pretty fresh. What else do you guys look for and check while under here?

Check the crank and rods for obvious damage or cracks, give everyhting a shake and make sure there's nothing glaringly loose. If your engine has high miles or hours now would be the time to do rod and/or main bearings since it's already open

Pulled the pan today and found a nice surprise. My rods already have the 12pt bolts installed.IMG_20190826_162816103.jpg
Now I gotta spin this big boy over and pull the piston, hopefully this goes smoothly

Ok well that was so easy it actually has me worried. Managed to spin the engine over by using the fan, got the rod bolts out and pushed the piston out. Or well, the piston AND liner. Aren't the liners supposed to be a real tight fit? Thre's oil between the liner and block, and the #1 and #3 liners also began sliding up when I was spinning the engine over. Is that supposed to be like that? IMG_20190826_173829134.jpgIMG_20190826_173835596.jpg

No, that is normal. When the heads are off and you spin the engine over, the ring friction is often enough to lift them. All but one. There is always one that won't budge. It's the one Murphy is sitting on while he watches you.

thats the one you have to put a bag of ice (in a large baggie) in the cylinder for a few hours.......

Ok, had me scared for a minute, I'd always seen and been told that any kind of sleeve removal, wet or dry, would always be a nightmare. Awesome, that saves me.a lot of time. I guess I'll get going on ordering parts.

I noticed that the head gaskets they have with that set look a bit different. My engine is an LDS-465-1A, TD block. Is there a difference in head gaskets between these and the -1D or -1C engines? I couldn't fine much online that specifies head gasket specs or variations. Is the change in shape and design just part of the modernized update?

LD, LDS, LDT 465 all variants- same head gasket. LDS 427 not sure.

I'm not sure which piston I need, I gotta check when I get home. I might just do all 6 rod bearings. The one I took out looked kinda worn so I might do all of them. If that piston is the same though I may be interested, I'll let you know
