Post Best Exhaust Manifold Gaskets...

Hello all, I recently upgraded to speedway stainless ramhorn exhaust manifolds. I used the included head to manifold gaskets, cleaned, torqued and re-torqued 4 times after warmups. Of course the gaskets blew out, so I'm installing new ones.

After the recommendations from this posting's subscribers, I looked up the Remflex gaskets. On SummitRacing they had (22) 5-Star reviews and (1) 4-Star review, that is an amazing success rate! I ordered a set and am awaiting their arrival. After installation and break-in I'll post the results.

Thanks all.

Re: 2 1/2" ram horn exhaust manifolds? Or something better?

Zombie alert. I really like this thread. Are there any prebent intermediate pipes that bolt up to the 2 1/2" ram horns? I'm planning on using two right hand Dorman manifolds so I get the nice bevel to fit the doughnut.
