72 911t 2.4T leakdown & compression results

I spent a couple of hours testing the condition of my stock 2.4 MFI with 90k on it, the engine has had no major work done.
It was tested warm, and retested to check accuracy... I did a complete tune up including valve adjustment about 500 miles ago, mfi, timing and every thing else is spot on. The #1 plug is always very dark.

The results:
#1 18% 80psi
#2 7% 85psi
#3 8% 83psi
#4 7% 100psi
#5 9% 90psi
#6 6% 92psi

It seems odd to me that the left bank would be so much lower on compression than the right. The engine starts and runs fairly well, it had sat for several years at the PO's garage. I"ve dropped the motor, cleaned it up, replaced all the easy gaskets and seals already.

Would you rebuild at this point?
Any one have a free 3.2 they want to get rid of?
