ive herd that i can push through 3-4 ball bearings of the right size to reshape a dented intake runner. who has done this and what size bearings do i need ? many thanks ant

measure the inside diameter of a runner and go from there

be carefull when buying kits to do this with. Some are wood and the balls themself will deform.

I bought a kit off ebay from some user. After several weeks of emailing and fileing a complaint off ebay, and posting here. I found out the person was a member here and I finally got my money back, but no product.

I ended up getting aftermarket runners.

I have a set i'll sell. I need to check and see if I have undented them yet it's been a slow project. I think it's a set of 6; 5 one size and 1 over size you can use a hone to open up the flanges that ball is like .020 over stock size they are all steel. I'll sell them and mail them to you for $45 I have an ebay account that shows I am in good standing if you want to view it account name chevrolet_guy
