Has anyone ordered/installed these items yet? Stage 1 head port and polished and pistons from ZPI?

I'm looking to order both and was wondering if anyone on here has them? If so can you give me some insight on how you like them.

If not! hey, ZPI can I be a guinea pig

actually besides matty, i don't know of anyone that purchased the head. Supposedly ZPI was also doing one with valve work and I've been waiting for that one.

I'm curious if someone did purchase one, did they get the same power gains that zpi claims?

Yeah i'm really interseted in this package. they say on the site that it increases airflow by 38%. (i think) I'm assuming with my header and exhaust the power gains should be well over the 21WHP that they claim the head adds.

custom dyno tuning is whats really got unlock the potential of the head package.

They've been purchased, but, to my knowledge, have never been installed on a tC... it seems like everyone who purchased them had them up on classifieds a few months later...

The install for a P&P head on a tC is WAY NOT CHEAP.

ZPI said they'd do it for one of the other guys, maybe you may get a break on install if you take it there.
