I know there are many here who say not to use the cork gaskets on the china walls but I do, and while the “no gasket just RTV is good”, when contemplating that method all that comes to my mind is this: Biggest issue is cleanliness. You read the instructions that Felpro provides you ensure an oil free surface, I bend the little head gasket ears/nubs up a little, run thin beads of rtv ultra black at each corner of the head/block junction, peel the paper from each gasket and stick them on the clean dry block, making sure those head gasket nubs go into the little holes, then I push the nubs back down to how they were, then run a bead on top of the gasket/head junction to fill in the small gap and then install the intake otherwise dry. I’ve done this countless times with never a problem with leaks, squishing out of the cork gaskets, and removal and cleanup of the intake is easy. The key is cleanliness and following the little instruction paper they provide with the gasket set.
The only problem with the gaskets on the China rail is the thickness. I try and run the gap much tighter than the thickness of that gasket. I can hold the intake up.
