[Bolt Torque] Bluetop head x Redtop block

[JonnyAE86]

Currently overhaulin an engine for a client, thing is he already bought the car with a redtop block and bluetop head.

How much torque should in the head bolts? Kinda confused and dont want to mess this up.

Thank you for your time

i guess it depends, do the torques differ from engine to engine?

There's a site out there with torque specs for engines from an AE92 (redtop i presume?)...

I'd say, depending on where the screw actually screws (or are both parts threaded?) go for a middle ground, or just torque it up to the bottom part spec (redtop block specs)[/s:a01cf5d775] (edit: robokill's suggestion sounds way more logical than mine)

then again, you might ruin the bluetop if the specs are way outta line.

The 4AGE manual, is that for a bluetop only? (it seems for AW's as well, they're sideways... but also bluetop?)

I will bolt it like a regular Bluetop:

300kg , +90º, +90º

Thanks Pardal for the help

cavey thank you for your help too

As the head of the 4age is bigport always bolt it to those specs. The lower block is cast iron and won't crack while the head can!
