BBk shorties do not play nice with the trickflow heads. I had to take some material off of the passenger side head to clear the collector. It was hitting the head way before the flange sealed to the head.

Hmmm...well hell..if they don't work ill order something. I sure hope they do! I wonder why they fit different on TFS heads?

Question: Whats your turbo setup Chris98Gt?? Numbers?

I assume they just have extra material in that area on the trickflow heads. I've got the first gen on3 turbo kit with a turbonetics 62-1. Made 513/484 @ 13psi. I've got the forward facing upgrade kit, just need to get a upr kmember and start swapping parts.

Wait wait wait.... people build rear facing turbo setups?! Why?! I also don't understand if they are building you a custom turbo kit, why they can't start with a set of shorty headers and chop the primaries and re-route them to either be a straight dump or forward facing. This should not be that complicated if they are experienced in this.

Very good point haha. Ill see what the guy that's actually gonna build the turbo wants to do lol.
