351 C intake manifold sealing/gasket uncertainty..

...The Metal 'Turkey Tray' IS The Gasket!
The Embossed Edges around the ports are the Seal and the Composite Gaskets are Not Used.
I believe the Rubber END Gaskets Are STILL Used with the Tray.

I Eliminated the Metal Tray, Years ago, IMO NOT Needed. Now, I just use the Paper Gaskets with RTV as the End Seals. Apply a Wide Bead of RTV to BOTH Contact Areas(After De-Greasing), when It just becomes 'Takky', Drop the Manifold Down. Doesn't Leak a Drop!!

...Make it Easy On Yourself, and Use 4 'Studs' on the Center Vertical Holes, to help Align the Manifold Perfectly. Once Installed, Start All the Other Bolts, THEN, remove the Studs and install the (4) 5/16" Center Bolts.

Marlin too fast for me..

1) I have a new Edelbrok Intake manifold. RPM Performer ! Below side is fully "closed". It sits on new Trick Flow heads..nice fit (so far)

SO CAN I SKIPP the METALL TRAY and use the nice Gaskests (picture above) for the Intake instead?..WOULD BE happy to do it as much easier..(sure will use the 2 silicon gaskest on front and rear!!)

TX Matthias

Correct. The metal tray is not required.

I think you have the wrong gasket(shown on head)
check with Trick flow, the gasket should match the intake port better. I think you have a 4V stock Ford gasket on 2V heads. Get rid of the metal splash pan / gasket that is for a stock application along with the rubber china wall gaskets,use R.T.V. silicone to lay a bead on the china walls and a little around the gasket ports if needed. This is instructive : Small Block Chevy Engine Build: Intake System (Part 2)

wooow again.

No Metall..Turkey!!! Top.

will order the correct Trick flow gaskets .. interim using the BIG stuff..

TX again .. on a long learning curve...may be 70%..

Top US TEAM!!!

We all have to learn, watch that U-Tube Small Block Chevy Engine Build: Intake System (Part 2)
It may be you should talk to Edelbrock on the intake gasket, even though it is a Chevy install it is a Performer intake and really they both go on the same way.

Yes!!! Junk That piece of Tin Pan! I have two Pans, Sitting on the shelf. I Can't Give Away!! And Yes! You need the 2V Gasket that matches. And Install those gaskets Dry. No Sealer needed.

...one tip, on those RTV End Seals...Just as soon as You have all those Manifold Bolts Snugged Down, Take Your finger and Run it along the Excess Silicone, that has oozed out, smooth it down, in and along. After It Cures, it will look Pretty!

You can only use the 2V gaskets if your intake manifold is 2V port sized. If manifold is 4V and you use 2V gaskets you will have huge vacuum leaks.

It is important to note that when you start to modify your motor you will and must use comparable parts, their are a league of gaskets to chose from explain your head and intake combo to a tech at either company, they will direct you to the right part.

Tx Team will do...

if you install the silicon sealing bead type gaskets dry they'll stick & tear during torque sequence, they actually need to be lubed so they allow the intake to slide into place. we call them Printo-leak's http://www.network54.com/Forum...19/thread/1355973452

old school paper Mr Garbage all day long for my $

Mr Gasket #211 would be the correct gasket for your heads

www.holley.com/products/gasket...ke_gaskets/parts/211

as mentioned above & in the you tube vid, throw the cork end seals as far as you can!

they make great cat toys

I make my own intake gaskets out of regular gasket material. Port matched and no leaks. A bit cheaper also.

Tx Team,
well will go for the #211 AND USE the SILICON Rubber for both ends vs the toy cork(s).
Saves me experimenting on custom components.
