Scored this today...

[homelessduck]

The machine shop said the head was good. They said one fire ring was a little fuzzy and asked if I wanted it surfaced. What do you guys think? It seems like I've read that you have to be really careful surfacing these but I can't remember why.

I don't know the specs, but because these have relatively high compression, any more than a couple thousandths will result in the pistons being too close to the valves. They should be able to surface them without taking more than 0.003" off.

On the tap, you could just cut the end off, put a bit of chamfer on the first thread, and voila, a bottoming tap.

Picked the head up from the machine shop today. I had them resurface it. Working on pulling the engine now, then I'll drop the other head off and have it checked out too. @sjwelds thats a good idea. I'll just cut the lower part of it off

Dont use a tap, cut some slots in an old head bolt and use that. a tap may cut deeper making the threads loose, and for all those that have done it with no issues, I dont want to hear it.

Working on pulling the engine today. Had to stop and snap a picture of how clean this thing is. I'm REALLY hoping no rods were bent from hydrolocking. He said it happened over night, so that's better.. but i know these starters have some torque.

Engine is out. Dropping other head off at machine shop tomorrow. When I disconnected the coolant heater hose I found this... Completely plugged.

So you're saying that the heater didn't work very well?

Good point, thanks

Sooo, found this under the other head. Back cylinder had water in it. Definitely not coolant , so thinking rain water. Whatcha guys think ?

Also- Aside from tearing the block down, is there any way to tell if a rod is bent?

 

[DaveBen]

Place it on paper and draw the outline, then flip the rod and place it over the drawing and see if it matches. Rods do not bend .005 inches, more like a quarter of and inch or more. It is usually obvious.

I really didn't want to get that deep.. lol.I don't have a clean place to do a complete rebuild right now, and that is what would happen once my ocd kicked in haha. I think I'm going to just toss it together and cross my fingers.
