New head doesn't match my 87' 22RE
First off, new to YotaTech, want to say hi and glad to be here!!!!!
OK.
replacing timing chain and head, ordered new head from J&C Enterprises. Went to install new head and couldn't torque down, pistons hitting head. The pistons are dome-shaped, starting to sound like its an engine that was originally turbo. I don't know the history of this vehicle. But there is a bunch of s%$t in the engine compartment that isn't being used, and the manifold is not original.
Pretty sure the exhaust ports are pear-shaped on the old head (shipped the core out yesterday, don't have it for reference til next week).
So......pear-shaped exhaust ports and domed pistons.
Any thoughts.

Thanks for the link. I'm really starting to think its a 22RT-E, sans turbo. That could explain why the engine is so gutless. I'm probably running an engine that was designed to have turbo.....without turbo. I did some reading about the different 20R series engines and the only one with "dished" pistons is the turbo.

I don't think it's a turbo. The turbo block is easiliy ID'd by having an oil feed on the drivers side rear and an oil drain about mid way, bottom of the block, drivers side.
22RE with 22RTE pistons? Unlikely. The 22RTE pistons are designed to lower the compression over the 22RE pistons. That is, they're not going to have as much area.. Here's a photo of 22RTE pistons - they're basically flat. You'd be less likely to hit with 22RTE pistons.

If I recall right the 22R/22RE pistons have "crown" on them.
Can you post a photo of the pistons you've got? I assume they're sticking up from the block somewhat?

Those are the ones! Those are my pistons.
Thanks for the info. No pics, it's at my mechanics house and I'm hard at work here, obviously. But i'm pretty sure that's what my pistons look like.
All I know is that I ordered a 22RE head, and the pistons I have are hitting the head before it can be torqued down.

mechanic said the pistons looked like they have a "pop-up ring" in the center of the piston. That tells me that it's a turbo, going off of the above pics.

The center of the turbo pistons isn't raised.
Have your mechanic check the deck height. I wonder if they screwed up and sent you the shorter block with early pistons...

Didn't the early 22Rs come with different pistons to accommodate the taller deck height?
Was your timing chain single or dual row? It's sounding like you have an early 22R block in there.

I took me a bit but here is a link to identify the blocks.

It looks like someone who owned the truck in the past installed a new engine, but thought there weren't any 22re's available (they must have lived in Afghanistan..no wait, the Hi-Lux is the official truck of the Taliban). So I'm thinking that there must have been a 22rte laying around w/o the turbo and they stuck it in.

I'm wondering if you have a pre-1985 block....
Take a few photos of the block deck with pistons in it and the head.. Post 'em.. We'll have it figured out in no time. That's the easiest way to help you...
Here are a few more photos that might help if you don't want to post pictures.. notice the differences in combustion chamber:
1) 22R head - goes with an early block:
2) 22R Piston in the block.. ignore the ring debris:
3) 22RE head:

yeah, that's the same head the vendor sent me. So it may be a pre-1985 Block. I'll find out next week when the vendor receives my old head(core) that I sent to him. From there, he can take a look at it and tell me what I have.
Thanks guys.
I'll update after I get some info.
