putting the bus back together, some inital head questions

[chachi]

refreshing this CA case motor i got a few years ago, running with decent compression. ran it with a progressive for awhile till the progressive stuck open, so i got my original PDSITs rebuilt and am now mounting those, giving it new seals and running it. tearing into it, i noticed a couple things. one of the heads has some some marks, probably where somebody pried the manifold off with a screwdriver. how bad are these? luckily they're at the outside edges.

also, i was delighted to find what i can only assume is a head temp sensor port drilled on the 1-2 side. or is that not what this is...?

also, i have tried to find some source for manifold to head gaskets for awhile, and i think i even posted here asking about them but never found any. am i just going to have to cut them out of gasket stock?

those are EGR ports, they get blocked with crimped old exhaust gas port stems, or threaded valve adjust screws.
The gaskets for the intake, the best would probably be from CB Performance.
The true temp sender for FI threads off to the side of #3 cylinder, and you can see the threads from the outside.

This is the early TSII sensor location, if you use it you should probably add the extension that moves the sensor further from the head. It is also a PITA to access the TSII sensor in this position and you need the correct hole in the tin and the grommet for the hole. I would not recommend using it for those reasons.

This drilling would be for the later TSII location. The same location was used for the air injection on 73-74 models, in that case the hole would be deep and go through into the exhaust port. The easiest location to service the TSII sensor is on the #4 cylinder. You can see what you are doing and reach it much more easily than when using the hole next to the #3 cylinder.

Are these 1800cc AMC heads?


Your dings are of no consequence but maybe run a flat file over them to be sure nothing is sticking up above the mating surface.

thanks for the info on the TSII port. i haven't verified whether these are AMC heads yet but it does have an 1800 fan shroud. i probably have the tin to use this location (i have a mountain of tin) but access is a valid concern.

bad news last night. got the oil cleaned off the top to find this. guess that's what that "G" stamped next to the engine code is all about and i'll be building another motor sooner rather than later.

I've got one of those-- it's in blue bus right now almost brand new- If I'd known, I'd never have bought the bus- but now - after changing out the lifters- (ya they failed before the motor got dirt on it) and the cali hacked exhaust, It's starting to run better.- I'm still going for a replacement on a pallet ready to ship before any extended trip- Any one had success with GEX???

It looks like it has been a long time sense GEX touched that engine,may have been a good one,or someone may have worked on it after GEX got done with it.
