So for many years I used intake gasket sets that had little yellow plastic pieces that fit in the gasket bolt holes (2 per side) and kept the gaskets in just the right place while installing the manifold. There is even a little recess in the heads that accommodates these clever little devices. The Felpro gaskets that I just got don't have them. Anybody know where I can get some or what brand of gasket they came with?
I just silicone around the water passages and that holds it fine. Many of the aftermarket parts do not have a provision for the plastic guides.
I usually buy these ^^^ gaskets just for the line up plastic plugs, then I use my own preferred intake gaskets.
I use these Edelbrock intake gaskets on the 360 intakes, along with the plastic line up plugs. Prices are going up on everything, at least the shipping is free that helps.
3/8 plastic hole caps. Just cut the base off to open them up. Cheap most hardware or fastener stores. I just grab them from the shop. Steve has a drawer of diameter assortments
