gn1 head and intake install ?

[bird]

re-installing my gn1's with felpro 1007 gaskets with receiver grooves. should i torque the intake manifold before the heads? just wondering what the benefits are? and whats the proper procedure. Is their any risks to doing this with the reciever grooves.
thanks.

Torque

I have one spec. saying studs @70ft/lbs and intake bolts @ 25-30 ft/lbs .. both with lube on threads. Would seem that with the number of studs + torque value holding down yer GN1 heads, the intake could be done last.

I believe i ve read to finish torquing down the intake before the heads to assure a good intake fit. Cause no way if you torque down the heads first will you be able to pull your intake in where it needs to be .

49 is right. You have to do it that way to avoid intake leaks.
