Dan .... X2 on what Bob Cowan said on the silicon sealant . I used that on my 63 1/2 Galaxie 427 with cast iron headers with zero leaks since I put them on 8 years ago .
Same for my ERA/Ponds 482 . Used the copper silicon ( hi temp ) stuff when I put the primary pipes on over 4 years ago and zero leaks . A whole lot easier to use and no cuts on the hands .... also a lot cheaper .
I also used silicon on all my dirt cars when racing and had no leaks .
Why use gaskets ????

Bob
