i did a compression test while swaping the headers.
1-160 3-165 5-165 7-160
2-160 4-165 6-170 8-160

How do these look for a 350 tbi out of an 88 truck

 

overall look good to me. From what I have read that actually pressure doesn't really matter, but what you are looking for is drastic variations between cylinders. Something like you want them all within 5%. Sure someone will pipe up with correct number, hehe if that isn't it.
