Anyone ever run more than one intake gasket before? What I mean is, have you ever run two gaskets instead of one between the head and intake? :-k

If so, how did it work out? :-k

Ken,, I have run a thick and a thin for a some time on the Vega never had an issue...But that was with gas.........Honestly I don't think it will work for any time as it needed to be tightened now and then..
A 120 thick gasket won't do it???

If I had to do it again I think I would use a felpro gasket as there more of a hard board type and not soft like others. Glue them together and go from there..

BLP keeps gaskets up to I believe .125 for a lot of heads, 18 degree should be no issue.

Ken,

You might want to consider making your own intake gaskets. I know the ones I've made myself in the past always seemed to last longer then ones I'm bought pre-made. Should be able to get gasket material in thicker the .125 thick. Real easy to do.

I have ran 2 intake gaskets with very good luck in the past. Last time I did this was on a circle track engine that was together for 2 years before it was tore down. It had no intake gasket problems at all.

Like Baretta said, I used black silicone on my intake gaskets and between them.

How about offset head dowels in the block, to move the head up on the block?
There's sometimes other benefits to doing that.

Not a bad idea Randy. I would want to pay close attention to how this would affect piston to valve clearances.

I'm still waiting for a return call from Sonny's welding guy. When I called him he said he was going to call me back after he got off work. Ask me how that has worked for me??

I'm not going to beg some someone to do work for me. If it's that much trouble just to have him look at it now, then just how long would it take for him to actually do the work? I've got an engine to go through and time is running out. I want that engine back in the car and running when racing starts up in March.

Anywho, if I don't hear from him by the end of the day today, that manifold goes back in the box and will be sent back! That tunnel ram worked well enough this past year that it will work next year also! ;-)

Why not put a single dominator top on the sheetmetal intake? Bob

Hood scoop clearance! I want to run some kind of filter to help straighten the air around the carb and with the T/ram there is NO room for anything without major modifications to the hood itself. That and I think that single carbs on a tunnelram present even more problems with lean corners than a regular single intake.

Ken why not make a spacer??? Like the short deck intake on a tall deck block??

With your machining skills I would think it would not be too tough for you..

Believe me Barry, that thought has crossed my mind but the problem with that is then there's two gaskets to fail from the methanol. I could probably use a 1/4" spacer and two .030 gaskets. That's how far it's off!

The good news is that the manifold welding guy just called and I'll meet with him this afternoon around 4:30.

EDIT: Another thing is how to seal off the intake valley with the spacer in there? As it is now I'm probably going to have to seal that off with RTV as I don't think there's enough material on the bottom of the head on the intake side to seal it that valley cover.

Ken,

The end rails are no big deal at all. I just make aluminum spacers and mount them by drilling and tapping the end rails. Using counter sunk allen heads to mount them. But you will need to think about the distributor gear height. No big deal though if you have the adjustable collar on the distributor.

Welding is the correct fix in the long run.

Don

when a .125 (MG 122) wont do it I have a local water jet cutting shop cut some alum shims the thickness I need and sandwich the alum between the MG 121 gasket I usually use. They made a pattern off a gasket and modified it by elongating the holes about .060 top and bottom for fit. It turns out to be a neat fit. If the spacer plate is thick enough I will pin it and the gasket to the head side and let the top gasket float. When the intake comes off all you have to change is one gasket.
