Snakebit:

Were you trying to create a Small Block Hi Riser:D

Glad to hear you found the root cause by being diligent.
blykins is right , Someone using two gaskets is a sign from the engine gods! Find and fix the root cause of the deck height to cylinder head intake flange mis match, and have the parts machined correctly. This is a dynamic joint and over time using the two gaskets stacked like you describe will cause a problem again as move in normal hot/cold cycles. It will be a high maintenance joint and will require more frequent tightening. If you must, find or make a custom thicker single gasket, but stacking 2 gaskets is risky and a temp. measure only. I could see this as a quick fix between rounds at the track but not for a street driven car. If it was my engine I'd take it back to the "professional" builder and make him stir his daily coffee with those doubled up gaskets so he remembers. :JEKYLHYDE\
Buts thats just me since engines cost so much.

Yes the blue Hylomar is good stuff, racer supply houses carry it, I did same thing as snakebit .... I used the Permatex RIGHT STUFF sealer on the ends of the intake manifold and saved the cork end pieces for the wine!:3DSMILE:

This post is about aligning the intake gasket, intake ports and head ports on a small block, AFR 205 heads, Edelbrock manifold, Mas-Flow injected motor. The motor also had TWO stacked 0.60 gaskets, on slipping on the other causing part of the failure.

I'm going back together after finding out the oil consumption and pinging was a failed intake gasket that had slipped during a previous installation and finally started leaking at the bottom valley side. Sucking lots of oil.

The AFR head intakes ports look great and the Edelbrock manifold has been previously worked over it would appear and also looks very professional. Intake manifold ports measure slightly smaller than the head ports, which I'm leaving alone of course.

The motor is in the car, I lifted the intake with great care and covered up everything to keep trash out of the motor, propped up the intake on supports above the motor and got busy. Installed 4 studs at the 4 corners of the heads to align the intake. Matched the intake gaskets, SCE premium 0.60 to the heads.....and now my question. Planning on glueing them down with Hylomar and letting it set up overnight to avoid the slipping.

Question and concern. Is there a magic trick or easy way to drop the intake on the head and see where the intake ports are aligning with the head ports or intake gasket? I want to make sure it's not dropping to deep on the heads and would also like to see if the side to side alignment is at least over the head ports and no lip is left on the head port side.

Hope this makes sense. I'm really ready to get it going again.

Thanks.

I had a intake go bad on my SB. It also was a double stack gasket. Talked to Keith Craft and they said it lines up the ports for better flow. They use 3M window sealer between the two gasket, let them tack up then stick them together, put a book on them for weight. Same for the on to the head install let it tack up on both sides then stick them together, "go to lunch" then install the intake. It was easy to do and has worked well.

from my experience with Hylomar, you won't have any trouble with slippage. It is extremely sticky. I use the Hylomar Racing Formula, which is the one that Permatex markets for them.

You will find out about the sticky factor when you try to get it off your finger w/o resorting to caustic gasket remover.

The SCE gasket is .120 thickness instead of the standard .060. It is made for standard ports, so you have to trim the port openings to fit your heads. The SCE part number is 136106 for a small block Ford

All fixed and this should close this post.....
 
It's fixed. It runs perfect. No black center plugs, no smoke from exhaust and it idles back down immediately.

For those of you having the same oil consumption/ middle two black plugs, pinging at low speed acceleration.....a new intake gasket fixed the problem completely. Installed it with Hymolar racing blue. Stickiest stuff known to man.

The last issues was refilling the cooling system and getting rid of the air. Lots of posts on strange ways to do it on a small block. After a bit of frustration, I just decided to unscrew the water temp sending unit on top of the manifold and fill the tank until water came out of the sending unit hole. Screwed the thing back in and haven't had a problem since. Water level and temp is perfect.

Thanks for all the help and advice. Taking that thing down to the open valley with the motor in the car was the easy part......unplugging and plugging back in the FI system was a challenge, but I learned a lot. She is good to go and I'm back on the road. Yahoo.
