riser gaskets

Hello,

I have a 98' BY model 5.7L GSi and just had the Osco risers and manifolds sand blasted and surfaces done and have the new Sierra gaskets that came with them.

I would like to know what other people are doing to ensure the riser/manifold connection gets sealed properly?

the volvo manual says to torque the bolts 12-18 ft.lbs. which seems to light to me for 3/8" bolts, also what about sealants?

thank you for your help.

Ayuh,.... I throw away the green paper gaskets, 'n use the carbon/ metals 1 I get from Mercruiser,...
Donno if that'll work for a Volvo...

Anyways, gaskets go on dry, 'n I wrench 'em down to 'bout 30ft.lbs..... typical 3/8" bolt specs...
