Talked to TTI. No real help. Since these are 2" headers on a low deck he claims that is attributing to the problem. I bought these headers knowing they were big so I didn't have to buy things twice when I build the larger CID stroker.

Anyway, he also said the slip elbows need to be cut down on occasion.

So, I am back to modifying things, or sending them back. Considering the restocking fee and shipping I need to think this through. Maybe someone local can make me some proper slip elbows. I'd rather not have to cut the heck out of everything.
