Disappointing TrickFlow news to report

Not sure I want to replace 8 seats because I’d probably have to do the exhaust seats too because of the way the bigger seat would interlock.
Naaaa, dont mess with the exhaust seats, just cut in the bigger diameter intake seat, it will interlock, but just retouch the seat when your done. Easy peasy. I like to tig weld around the seat insert, they just fall out when they cool.
