Percy's Gaskets - Circle, Square, ?

I just picked up some of Don's headers and was wanting to get some Percy's header gaskets to seal the deal.... hehe.....

I took a header to Autozone to compare. The CIRCLE manifolds didn't fit right, and the SQUARE didn't line up perfectly either. Hmmmmm.

I'm using stock 416 castings, so I went ahead and bought some cheap Felpros for the meantime that I've used before with logsl

I've always covered the header. If round, I use round

only use percys and have been leak free since I began using them on all the cars
