What do i torque my manifold to on AFR heads???

22 ft/lbs with oil is what I do. No issues ever

ive always used 24lbs in the correct torque pattern

Now AFR told me do not torque the intake down.. Just snug it down good. Take a very good chance on pulling the threads out.. But that was 3 years ago...

This info is included with the booklet you get with a new set of AFR heads
so what you speak of is good advice for sure.

I refrained from using the word ... Snug ............. Well because .........

My idea of snug is most likely not the same as your idea of snug

Just for the heck of it ..............
After snugging up my Edelbrock lower

I found my torque wrench clicked at about 15#'s on my combo

The idea here is to get an even clamping force through out the entire
length of the manifold

I did mine in two steps of tightness with half in one set of sequences
and half in the final set.

After a couple of heat cycles you will find some will be loose
so it is a good idea to go over them one final time

I do not use rtv or any kind of gasket sealer on my gaskets as
the gasket itself is for that

Yes ... a litle dab in the corners of places like intake and front cover

Anyway ... You'll end up with two main thoughts here

I don't wanna hose up my soft Aluminum threads
but yet
How tight is tight

A torque wrench can put us all on the same basis of tightness.

Now ... The official Ford Service Manual calls for 23-25#'s
but ...
Oem conditions are such that you tighten bolts in threads of IRON heads

I can only share what has worked for me

I use antiseize on intake bolts since they are going into aluminum for the couple reasons that final5-0 stated.

I use oil for engine lube, not bolt thread lube
