Why don't the water passages match on these? Both are Edelbrock Performer parts...

Any tips on installing a manifold? I would have bolted them on tonight but the Mr. Gasket set has more material than I like.
I have Permatex "Right Stuff" and "anti-seize". Attached image(s)

Hi Neo
Permatex ultra black is my choice, clean the area with brake cleaner, dab of silicone in the corners behind the gaskets, install side gaskets, I use a special spray called "High tac" to keep them from sliding around. Nice thick bead of Ultra Black, and your done. The only intake issue I know is some heads will allow an overlong intake bolt to touch a push rod, double check this before you install the valve cover. Good luck with it Joe (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif) |

I agree with Joe. Use the Permatex only on front and back. A trick to a neat job (not that you can see it in a 914) is take two strips of masking tape across the intake and block outside surfaces and lay in a thick bead on the mating surfaces. Install the manifold and use a damp finger to wipe off excess, then remove the tape. Remember to use thread sealant on the bolts, many are open to oil.

Sean, I figure it is designed this way but the center galley made me ask the question. The gasket I removed had an opening but the one I just bought has none. That wouldn't have a symetrical issue being in the center. Thanks for the tips Joe and Guy! |

So use the sealant instead of the supplied rubber seals, correct? Put sealant under the head of the bolt? I plan to use anti-seize on the threads. |

Yes, RTV sealant only on the front and rear block rails. Use Permatex Teflon thread sealant (white stuff) on the threads. It wont do any good under the bolt head. |

That opening in the center of the manifold is for exhaust heat to pass under the plenum in the manifold, for smog compliance and/or cold drivability concerns; from the pic, it appears that your heads don't even have this heat riser port open. Some gasket sets come with the gasket opening for this heat riser but include a small tin block-off plate to allow you the option of "plugging" this opening. The coolant passes from the block, through the heads and then out the thermostat housing in the front of the manifold. It doesn't pass out the rear of the heads due to the location of the distributor; some racers will, however, install fittings and a hose to allow circulation between the heads in that area. Some smog manifolds also have coolant flowing beneath the carb/TBI plenum location. Ron |
