ok thanks guys ill check into both places and go from there do you guys think i should gte my heads ported what are the advanges and disadvantages of that?

[travelers]

Its all depends on what your plans are. They already flow pertty good now.

The $$/hp ratio is horrible on ported heads.

You are lookig at a 4-9%hp gain on a NA motor. A couple grand for 12-27hp is a pretty lame gain.

I thought it was around 40-50 hp gain for heads and im also going to do cams at the same time?

I talked to Ron at fox lake and he saidf he dose not do the install himself he just dose the porting and that sort of thing so now i think i am going to check into Livernois i heard that they do some very good work there prices dont look super high either anyone have any experience with them?

Who did ur heads? and what cams did you use? I thought it was more than 12-27 forsure because if i can get that i will be happy.

[jgon08]

That is 61 at the wheels right?

You didn't mention aything about cams that I read

Those cams (490/.480 lift 222/235 duration @50 115.5 LSA) should net you 9.8% so your overall total gain should be between 42 and 57hp which is awful close to what STL got and that could all be down to cam timing, tune, dyo used, etc.

If you are looking for big power and don't mind a lopey idle the stage III cams (.540/.561 lift 242/250 duration @50 112 LSA)
with lock outs set up correctly can get you up to a 20.9%hp gain. That would put your head/cam mod between 75 and 90hp.

The heads are a big expense when you consider what they cost per hp though.

The cams are a bargain though. Of course they work together better with the heads than by themselves though. I think the heads are a bit overpriced anyway. With a little bowl work, unshrouding the valves, a good valve job (with quality valves) and some port matching, skim the heads a few thou to get the squeeze back and blending at the seats they will probably work as good as any CNC head. A FI motor would work better with the CNC stuff though. The OEM heads have a great design. They may be the best production head Ford has ever made. Gains are hard to find.

Ya ive heard that the heads are very good for what they are but im just looking to get right around 375 at the wheels without f/i and be done with my car for a few years and i think if i put a PnP and a good set of cams i shoud be very close to what i want.

I would give the guys at Livernois a call, and tell them what your goal is and see what they say.
