O.K., I have the Holley aluminum intake sitting here, staring at me. I want to use it but I hear bad opinions. Basically it seems that the main concerns are:
1) machining work to get the fit right.
2) bottom plate gasket has a tendency to fail?
or is it the head gaskets?
3) heat soak. (only an issue if you idle for a
long time.)
4) Egr set-up is less than perfect.
That seems to be about it. Unless you guys can think of anything else?
Now, on the plus side:
1) Port matching.
2) polish to make it pretty.
3) Extrude Hone for even more flow eventually.

So, when the intake is machined to fit, do the supplied gaskets do the job or should you look for thicker gaskets? Also, what exactely is wrong with the EGR setup? I drive a '99 T/A and plan to keep the EGR. From looking at all the posts i"ve gone thru it seems to me that the only real problem is that the intake is not a direct bolton. What are your views?

Cody, what made you decide to go with the plastic manifold. Was there just no way to get the aluminum intake to fit , or did you just give up on trying to find the right parts that fit?

 

2edybrd,

Do a search in this forum and you will find several threads with pictures on the Holley manifold, I may have been the first in the country to install it. They do heat soak, I make 3 passes and let it cool for about 1/2 an hour and make 3 more passes.

Cody,

You'll probably just have to make some new gaskets like I did, if I remember correctly I explained how to do it in one of the threads, or you can call Holley and buy them.

I have pics of my Holley intake done by GTP and if you do a search you can see it as it went on but we had to design a new plate for the bottom but other then that it was o.k.

 

Hey BadZ,

Why did you have to make a new bottom plate?

other than that, the only problem i've had with it is finding GASKETS and BOLTS for the damn thing. any help would be greatly appreciated, as i'm selling this intake and going with a GM LS6 manifold. even if i dont sell it i still need the gaskets and bolts for the day i install my new engine <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> i cant believe this search seems so totally impossible <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

 

also- i re-installed my EGR system as well, but i had to flip the o-ring gasket on the top air tube going into the manifold to get it to seal. try installing it as it is first.

 

So we could get full access to all the runners... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

BadZ,

Is yours port matched? Just out of curiousity what did Craig charge you for the polishing?

Thanks alot for the help everyone. So,Badz, you did not have to do any work to the intake to make sure it fit at the same angle as the heads? And the gaskets were mostly all good? I'm already going to use this manifold, I'm just trying to eliminate any surprises.
