525,600,700 header gaskets
 

Are you guys buying Mercury ?? or what

thanks

I use Fel-pro

Talk to Eddie Young he has some

I use cardboard and Kopper Kote.

Its a different pattern on the Edlebrock alum heads. Its not standard big block. Does fel pro make them?

525 efi heads??

yes 525 boltpattern... 525s are a spec head from Edlebrock if my info is correct

The merc gaskets are the ones we use ,if the headers have cool collars the mercs can handle the heat a lot better than the rest they also have a different bolt pattern than the stock bb

I was seeing if someone else had re popped these,

We have some MLS stainless steel gaskets made for the 525, 600,700. They are lifetime gaskets. You can not hurt them. If the header loosens, the stock gasket will push out. You then have to take the header off and remove the gasket and replace it. Mercury gets almost $60 per set. Our gaskets are a little more, but they will last forever. If the header comes loose and starts to leak exhaust gases, just tighten it back it. You WILL NOT blow the gasket out. They are $85 per set and worth every penny.
