Timing & Timing Mark - L69 w/ MAF TPI

What f-body motors had the timing mark right behind the water pump? It's not too much of a pain in the **** when the car had a carb, but now the air intake stuff blocks any view of it, and I need to time it.

Should I pull the air ducting, time it (yeah, I know how) despite the MAF code, and then put it back together?

What is stock timing for an 86 LB9 w/ 3.23's?

I think the carbed motors had it there, not sure about TBI.

The stock timing on an 86 LB9 is 6BTDC.
