Trying to put my car back together using the Felpro 1356 after 2 failed attempts with the turker tray gasket. Performer intake is not blocked on the crossover so I ordered the crossover plugs from Ebrock #2733. With the plugs installed won't the gasked just burn through or is this OK. Read a post where one guy cut a piece of the old tray and used to block the head. Won't this leak.
I'm lost.

Any tricks to installing the plugs so they won't rattle.

 

I know of a particular engine builder that fills Chevy crossovers with Hi Temp RTV and a ball of aluminum foil pounded into the head. 13 second cars to boot.

He has no issues so I would think if the heat doesn't burn through that, a slather of RTV and a peice of the tray will have no issues. I've heard using the gasket is fine as well. The turkey trays USED to come with some crossover covers...optional use of course.

I think there is a specific temperature resistant epoxy that can be used to hold the plugs tight and prevent them from rattling. Unfortunately I do not know where you can get it. I do not think the gasket would burn through if the plugs are installed.

 

I installed my Mr. Gasket gasket as per the instructions with no plugs or "pieces" of turkey tray. I've never heard about the cross over burning through the gasket.

 

I bought the crossover plugs from Jegs. They are metal not aluminum so I figured they belonged in the head vs the intake so that is where I put them. Just ground them down a bit to the point where I would only have to do some pounding. They fit like a charm. I won't ever have to worry about burn thru.

 

I got a set of those plugs with my intake manifold but decided against using them. I've also heard they can come loose and rattle.

 

We will see if this works, got it back together last night. Will try starting today with my fingers crossed.

 

Good luck. Keep us posted.

 

Looks sweet, post a video of it running. I love the sound of an Olds

 

I have only seen one set and they too were in the heads --Pretty sure that is where they are supposed to fit ?

Not thread stealing but does anyone know what hp may be gained ?? theoretically ?

I think this may have done it, drove about 60 miles and no leaks, sure seems to run better. (with wife had to drive my age)
I did install the plugs in the heads per the ebrock instructions sheet and filed progressive groves in the plugs for a better bite.

Thanks for all your help!

 

10-15 depending on what other upgrades you have done. But free horsepower is free horsepower.
