I wanna see a dyno, Green. =D Please? Hehee. I may pick up an intake manifold and get it ported as such (Though in my case, I'd be removing the VTCS butterflies, and opening up those two runners into one. Maybe install a phenolic spacer while I'm at it. =)). It looks neat, that's for sure!
Well take it as you may . the head IS GOOD enough for the power levels these guys need to run on the street. I guess you have worked on and turbo charged more than i have . I guess you have experience porting the heads and manifold on this car for two years like i had huh?twilightprotege said:
So i dont know what the car can do?
anyway linux nice post . We have talked about this many times.

Phenolic spacers....they have been around for years....they have been supporting the FS series motor with a great track record.

perf - i guess we were both victims of way to generalised comments
linux - that's why i try my hardest not to refer to porting the head as port and polish. port good, polish bad. polishing is only of benefit in the combustion chamber where you want to have no places where the unburnt fuel can hide. that's why i'm a big big fan of flat top pistons. any crevaces etc in the combusion chamber just allow places for unburnt fuel to hide (so to speak). also they can create hotter and colder areas in the chamber.
btw, my head will be taken off this sunday and being ported from tuesday

Are the spacers worth it? Not a bad price, so I guess so.
Do you still need the "regular" gasket with these? Two? Do they seal well enough on their own. Please tell us more.

I would imagine the spacers are worth it. =) I've not installed them yet, personally.
However, to answer the gasket question, many people go one way or the other; Get a set of two gaskets for either side, or they just smear a very, very thin layer of gasket sealer on either side. The gasket sealer seems to work better, and would be what I suggest, due to the fact that the gaskets would push the intake manifold even further away from the head than just the spacer. With that in mind, remember that there is rather limited space behind the engine, where the intake manifold sits.
Here's the FAQ page, which covers the question, actually:

626/MX-6/Probe guys have been using them for awhile now...We installed on of these into a KL-ZE (V6) and the reults are very straight forward. Before..you could not touch the intake manifold after a few minutes of driving....after....it was warm...but he could leave you hand.
It is not going to create horsepower....its going to reduce teh amount of heat soak..and give you that "fresh in the morning" horsepower you feel when you first drive your car.
