Good, maybe I'll have a set of headers for you to see in person. At least we can meet this year.
I know a guy who would swear the block split alot due to the mounts pulling on the block. I'm not going to say yeah or nah. But he did run 5.60's on a roller 351w all day long. Broken pistons from occasionally detonating, but never the block. He liked block plates. Said that cured it all for him.
