First gens aren't my specialty, but I have heard folks have had good luck with replacement heads from a company called "AMC" I believe...

ill check that out. by the way, dose any one want to buy a 1986 corvette with the manual 4+3 tranny? its not in the greatest of shape but it runs and has lots of power.

Clearwater makes the one I put in my Mitsubishi 2.6L Raider a couple of years ago. I worked like a champ!

I put an AMC head in the Trooper when I rebuilt the engine 4 years ago. It works great, as well, and I'll post a link to the site if I can find it again.

EDIT: After doing a search for "AMC" in the Isuzu Tech section with a time frame of 5 years, I came up with this... AMC Retailer. The AMC link on their site is dead, so I'd give them a call!

there are two heads avaible thru ebay one is remanufactured the others are new head (new casting) stay away from remans it not a question of if they brake its when they brak.dont take the chance a new head and gasket installed rightwill last forever. Not that much cost difference.
If yuo go to yellowstone you will beclose to my home in shelland anyone is welcome to stop. There is some great wheeling in the b BigHorn Mts.good luck DAVE horn

I got my head in from clearwater yesterday. it is so beautiful. i started taking the trooper apart this morning but it has been raining for the last few hours so i had to stop. i envy you people who have the drive to clean your garages <img src="/forums/images/graemlins/smile.gif" alt="" />. i did do so gnarly damage to my thumb though.

that hurt a little. now i know not to get in a fight with the machined edge on the cam gear. any way lots of fun, ill post more pictures of the heads and so on.

i got the head out of the truck today. the new head looks so good next to the old one. [img][image]http://i666.photobucket.com/albums/vv25/SAW32rally/head001.jpg[/img][/image] the old one is just not as well cast. there are a few spots were you can see it if you look close [img][image]http://i666.photobucket.com/albums/vv25/SAW32rally/head002.jpg[/img][/image] and the new one is shiny <img src="/forums/images/graemlins/smile.gif" alt="" /> [img][image]http://i666.photobucket.com/albums/vv25/SAW32rally/head003.jpg[/img][/image] the combustion chamber is cool to. there is not any real difference but it looks cool any way. [img][image]http://i666.photobucket.com/albums/vv25/SAW32rally/head004.jpg[/img][/image] [img][image]http://i666.photobucket.com/albums/vv25/SAW32rally/head005-1.jpg[/img][/image] this is just the engine torn apart. the cylinders still have the original hone marks [img][image]http://i666.photobucket.com/albums/vv25/SAW32rally/head006.jpg[/img][/image] this one is just because its cool to get a piece of hardware like this with your name on it <img src="/forums/images/graemlins/nana.gif" alt="" /> [img][image]http://i666.photobucket.com/albums/vv25/SAW32rally/head007.jpg[/img][/image] so thats whats going on. more tomorrow. by the way, there is a big enough difference in weight that you can feel it when you pick the up one after the other. swwwweeeettttt!

You'll like it when you get it back together! I know I did. Have fun getting the vacuum hose abortion back in. I know I did. <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" />

i figured that would be a pain. i marked every hose and plug that i took out with bright green ducttape so i should be able to get it without to much trouble. i dont know if i have reinvented the wheel here but has any one else ever put all the bolts each piece in a sandwich bag and marked them? i did that for the first time on this job and it works really well. any way, just throwing that out there.
