The underside of my intake manifold is full of sludge I have been instructed that the best way to throughly clean this thing is to remove the heat passage shield on the bottom. This is attached by four rivets. What I need to know is " after cleaning, would it be advisable to try and re-use these rivets, or should I try and find small screws to replace them?". Also, what is the best cleaning method you can recommend for this type of job

To clean, I think you're best off getting it chemically cleaned or boiled out. I have heard that the rivets can be reused and also that sheet metal screw have been used. If it was mine, I think I would either get new rivets ( they must be cheap ) or use screws.

We found this problem when we pulled the intake off of my dads 1968 327 last summer. We were having the heads re-done so we took the intake to see what the shop could do. The owner said no problem, he would remove the shield, hot tank the intake, check it for cracks, and reinstall the shield. When we got it back the sheild was on with rivits, I'm not sure if he reused them or not, but he did use rivits to reinstall it. Anyways the manifold is clean as it ever was now.

Garfield,
I have a box of small stainless sheetmetal screws that I use at the shop. They happen to be a size that works great just like they are. I have also tapped the holes for small screws in the past. Do not reuse the old rivits, they will not hold.

Gotcha. The only problem now is finding a place with the facilities to boil this thing for me. What would be the best chemicals to search for to clean this. "Believe me, I am becoming very tempted to just scrap this thing and buy a new one

The old rivets will hold just fine, but I wouldn't recommend using them. The reason being, that a machine shop is going to charge you anywhere from 25 to 35 dollars to tank your manifold, and for a few dollars more, you can, and should buy an aftermarket aluminum intake that will flow better, look better, in my opinoin, and will provide a great savings in weight. Unless you are a purist, and need the correct factory parts on your car, get the aftermarket aluminum, you'll be happy you did.
