Hi, getting ready to install the intake back on my 65. I was told not to use the rubber end gaskets but to use rtf sealer instead. What are the pros and cons? Thanks for your help.

The pro is that if you use RTV, you are less likely to get the traditional oil leak when the stock rubber end seal squeezes out. The con is that it won't look 100% correct. I throw the end seals away and use RTV myself. Be sure to build up a tall enough bead to reach the bottom of the intake, but not too tall that it squeezes out everywhere.
I've done it with both the rubber seals and RTV. With the rubber seals I use weatherstrip cement to glue them to the china wall, then put some RTV at the ends, nothing on top.
If I use RTV only, I trim the excess off the engine with an exacto knife after it dries so it looks somewhat flush. What makes the job easier either way is for all the surfaces to be clean of any oil.

We'll start calling you "Felix" then... I'm more of an "Oscar" myself.
use "The Right Stuff". I replaced two intake gaskets on the same car due to the end seals. Towards the corners they taper down and easily get crushed/leak. When I bought my car I had a mysterious leak and I could never find it. It ended up being the read end seal, an the oil would leak all the way back and down the transmission.
Finally I took the advice of a forum member and used the stuff above and it worked great. Trim it with an exacto knife a day after you set it in place.
Trust me, there are far more people who got burned usiing the end seals that those that successfully do it. Especially if the engine is in the car, much easier and more effective to NOT use them.
Also, careful when choosing the manifold gasket itself. I'll go back and double check, but if you're installing an aftermarket intake, I think you need the gasket for a newer car. They are only slightly different, but between the two felpro ones, it was enough for it to be a problem.I'll confirm the number when I get home for you. What a PITA it was....

There are three different metal intake gasket styles, at least for the SBO.
FelPro MS99471 is the two-piece embossed metal gasket for the 330 motors that uses the separate bolt-in valley pan to deflect oil.
MS96009 is the turkey tray for the 350 motors up to 1972.
MS96027 is the turkey tray for the 1973-up motors (note this photo has front to the left, the other two have front to the right).
Note that the newest one has larger openings for the exhaust crossover ports (probably due to EGR flow requirements or something). That's really the only functional difference among the three. I suspect an aftermarket intake will have the larger crossover ports also, so select the gasket that matches.

Thats all correct, thanks. I do believe I had to use the 027 for my intake. I left a review on Autozone's website to try and help out others, but they actually changed part numbers with felpro, there is now a PB at the end of each, so my review is gone.
The only other thing to note is that if you plan to use a one-piece turkey tray on an 330, you need to remove the original valley tray, as the gasket won't fit with it in place and replaces the function of it anyway.
I think you're right. I looked up "turkey roasting tray" and found a lot of images of a pan with V shaped bird holder, which is similar in shape to the valley tray intake gasket.
Now I can see the similarity of the turkey roasting tray to the valley pan gasket in the lifter valley.

I Like to use the Felpro MS 96004 for a b/b. Your 400 is a b/b if the original engine.
However I don't know if this one would be correct for the 65 400.

Hey, you guys are very helpful, and just the touch of a finger. Thank God for computers!
No problem. I'll note, however, that next time we could have avoided my whole side track into SBO intake gaskets had you told us you were talking about a 1965 400 in the first post.
