Compression Test Numbers before head install, questions

[conartist]

Did a compression test and got the follwing...

#1 - 125
#2 - 110 (100 sometimes)
#3 - 130
#4 - 130
#5 - 135
#6 - 140
#7 - 140
#8 - 125

Now my question is, I suspect that #2 has a problem, so I put some oil in it and re-did the compression test, no change. This leads me to think its a valve problem.

The motor is going to be getting a new set of aluminum heads next week, so my question is,

Do you think I have a healthy bottom end, given these numbers?

Thnx

The rings are weak with 80K on the engine... as well as the timing chain. If you are really excited on the heads... go ahead and put the heads on... just be aware that you DO need to freshen the engine soon!! cool??

Just me....................................

Thanks for the input thumper...appreciate it.

The heads goin on it are TFS TW's, I think I'll do the timing chain while I'm in there. The rings can wait til the winter
