Volvo 1000530 Cylinder Head Torque Specs

[FatRabbit]

Hello,
Looking for cylinder head torque specs for a Volvo 1000530 head.

The "Back Story".....Used to have the 1000398 head and the fourth port rotted out (wasn't sleeved). I believe the engine is an AQ125 engine but can't tell from the nameplate (corroded/faded). The boat is an '83 Bayliner.

I replaced the head and finding a ton of varying specs out there. Hoping to hear from someone who's "done it".

Thanks in advance...!

Welcome
I don't have a 125 manual, just a 120B/140A.
Head bolt torque list 110 Nm or 8.1 Ft Lb in 2 passes

here's from the aq125 manual

this is from the same manual, but the aq125b
the 125a was 2.1ltr
the 125b was 2.3 ltr
1983 would most likely be the 125a.
if you look by the starter there may be a tag that says what you have
