I don’t know if VICTOR REINZ makes the best 216 rocker arm cover gasket but it’s sure better than the FelPro multi engine gaskets (216 & 235) I’ve been using. As the image shows it does not have the 4 bolt holes most gaskets have. It’s strictly for valve covers that use 2 acorn nuts. I didn’t check the thickness (should have) but I believe it’s thicker than the FelPro gasket.
Part number is 15-10544-01. It’s been on the work bench for a few months so not positive but believe it came from Route 66 Auto Parts. Price was around $16 with a few dollars for delivery.
