intake manifold end seals

Always leave the dowl pins in for port alignment and make sure you check the alignment if you change intakes or heads.

Not checking this can result in a leak between intake runners. Which is hard to detect but the reason some run good and some don't.

A lot of these Mopar guys!! think they are there to hold the gaskets. They are only fooling their self. But some do get lucky.

Set the intake on with just the bolts loose and see how far it moves front to back. Look at the width of the web between the runners. Then you can decide.

An easy way on a low performance dual plane intake motor is to scribe a line on the top of each web onto the top of the intake. Align these with the center of the of the valve cover bolt holes. They are usually in the center of the port.

Some of the after market intakes are so far off I had to send them back. One line was center and the rest were 1/8 inch off. Nothing is 100% If you don't check your intake your stuck with it.

New intakes come undrilled this is because every motor is different. After locating your intake tap down on it leaving a mark from the dowls. Drill them to size in a mill so they don't walk. Taper the leading edge. This intake is now specific to your motor. This can be redone or moved for a different app.

I already bought roundy round motors where the intakes were staked in place. This was to prevent movement on Impacts. One of these motors came from Ray Everingham. stash . Bought buy Millers racing in Allentown. He purchaced alot of his motors in the switch. All small blocks and big block Mopars are like this do to the mirrored ports. BB chevy and ford have even spaced runners. Most All new motor designs did away with this intake runner issue.
