Removed an enormous amount stuff. Just removed anything that I didn't know what it was.
Next up is a good cleaning with a mini-power washer.

If you take the valve covers off and remove the tension from the rocker arms, it'll close all the valves for washing.
Save that hose from the power steering pump and the reservoir they don't make them anymore

That would have been a way better idea than my duct tape.
It was the 1000lbs HF stand. My philosophy with HF stuff is to get the model way overrated for what you need. So the 2000lbs version would probably be much better than the 1000.
Although having now owned and used the Summit rotating stand, I would probably still spend the extra $40 for it eventho the HF stand has a higher weight rating.
What head casting numbers?

Got the motor duct taped up, sprayed as clean as it'll get for now, and up on an engine stand.
Got the intake and drivers side head removed. Don't see any major issues so far.
Bores look ok on this side. I can see faint crosshatching on the walls and don't see any step at all near the top of the bore to indicate excessive wear.
Also measuring bore diameter seems like it hasn't been bored yet.dont know what the mileage on the motor is. Looks like still ~4.245".
If the other side looks as good as this side, I may just send out the block to be cleaned and checked out. If all is ok for rebuild, may try and install new bearings, rings, and put it back together. Just not sure about heads yet. Not sure if aluminum heads provide much bang for my buck anymore, especially in my price range. May want to spend that cash on other stuff.

I tried to do some stuff that would support a future build up if I wanted to get more power out of it. Would love to do roller cam and aluminum heads some day but damn they are expensive.
i know its sbc stuff but basic idea helps make a choice .
if your not going to spin it over 4k rps or so i say keep stockers .
if budget find a good set of 049 or 781 heads . large oval port .

Engine block is casting number 14015445.
Head casting number is 14081045. I think that's a later model open chamber head?

Yep there open chamber heads not Peanut Ports.... believe they come in around 119cc

Your gonna need a domed piston to get the compression up from 8-8.5:1. Cylinder walls don't look to bad you can still see some crosshatch....
What's the difference between those and peanut ports?

"peanut" is a term for the short oval (smallest of the oval ports). The defining characteristic of a "peanut port" versus a "large oval port" is that the peanut ports are wider than they are tall, whereas the large ovals are quite obviously taller than they are wide.

When I measured them, they were pretty close to the smallest port in that diagram.
This could be 2 or 4 bolt. If you don't want to pull the oil pan yet, you can see the front main cap with the timing cover removed.
What kind of power are you looking to make? Ebke has made some decent low buck numbers with no compression peanut port engines.

Honestly I'm no longer sure of what I want. I'm leaning towards being able to take advantage of any "low hanging fruit" that exists for power while keeping my idle rock solid. Dont need to get it over 4500 RPM.
I'd like a decent cam that can get me more hp/torque without ruining the idle quality too much. Looking at a comp Xtreme 4x4, x4 262H at the moment.
Fuel injection is also a requirement.
If the heads I have need more than $500 in work, seems like more modern iron heads might be a decent option? That might not be the case though. I can get whatever intake is needed and am starting to think seriously about selling all my TBI burning equipment and parts and switching to the Holley TBI injection.
