I have an 84 brat with manual tranny so solid lifters(right?) what is the torque specs for the 17mm head bolts?also what is the tightening sequence?I would rather not have to replace headgaskets anytime soon.

 

in other news tomarrow(err today being that its 1 am) I get the heads and assorted valve gear back from being hot tanked and the heads will be resurfaced.

 

also do I have to retorque the bolts?if so do I run engine,shut off,drain oil,pull covers,retorque,etc,etc?

Depends on your gaskets - retorque is usually after the first 500 miles I think. Fel-Pro's do not require a retorque (thus I've never done it), and many that use the OEM gaskets just go an extra 5 lbs on the initial torque to cover it.

 

Should be about 50 lbs final torque (55 if you are not going to retorque), but you need to do it in increments: 10 lbs, 25 lbs, and then 50 lbs. For the sequence.... you'll have to find a picture there's too many and I don't remember their numbers/positions.

 

Oh, and a couple sockets under the bolts for the rocker arm will allow you to torque them with the rest of the bolts and then install the rocker assembly later. That's what the book recommends - it's OK to take those two loose after the torque procedure is done.

If you use gaskets that require retorque, the retorque is done after the first time the car reaches operating temperature. (provided that EA81s are like the rest of the Subaru world)

anyone have a tightening diagram?

i'm new to this retorque thing, sounds like something I don't wanna do.... lol.

ok I got felpro no retorque gaskets so then smear a little oil on the threads and torque to 47 ft lbs.what is the three stage tightening?
