HEI Compression Test Question

[TJUCLA98]

Thanks for your input Dave, I am going to do a compression check very soon to see what turns up. I will report back asap on the findings. I actually had a Jeep CJ7 with a straight 6 that I did a complete rebuild on without pulling the engine as well. What made it easy was that it was lifted and had huge 35" tires on it. This might be a bit tougher to pull off with my truck being so low but it is doable.

OK so I just did a compression test, here is an overview and the outcome;

1. Brought engine up to temp.
2. Removed HEI Batt lead and spark plugs
3. Dry tested each cylinder, here are the results:
Cylinder 1: 100
Cylinder 2: 120
Cylinder 3: 100
Cylinder 4: 120
Cylinder 5: 120
Cylinder 6: 120

I did not do a wet test or leakdown (I don't have a compressor or air to hook up to). Realizing that I am still a step or 3 from really determining what the issue is, would you all say that the major issue at hand seems to be the "top end" - particularly the valve train for cylinders 5&6?
