I was wondering how much horses i would see out of a patriot stage 1 head for the ecotec? Would it be a better idea to purchase a patriot head or a s/c? I know a s/c gives you about 50 horses, i wasnt sure how much i'd see on a patriot stage 1 head. I think the head's are a bit less expensive than the s/c so a little less horses i figure?

Also, the patriot stage 2 head is just 200 more dollars and i get cams with that. Is that a better idea than the stage 1 will i see more horses? What type of complications could i run into, what should i expect when it comes to the installation of the head? Can i just buy a head throw it in the engine and not need any more parts? Are there any special parts that would be a good idea to get while doing the head instead of doing it half arse.

unless you do cams, and some tuning as well as injectors just go with the supercharger.
staying n/a isn't easy unless you go all the way... and will be tough to get max output from an auto since the torque converter takes lots of power.
altho, HPT has opened a lot of doors as far as tuning goes...
I have a stage 2 head with triflow cams... i'm looking to get more aggressive cams soon so mine may be going up for sale sometime in the near future
Just with the head and no tuning what would i get out of it. I'm not really to sure about the tuning.. i dont wanna start that and mess something up. I wouldnt mind doing the injectors though. What all could i expect out of a patriot head with the mods i have now which aint much, a catback header and a mount. I plan on doing intake and big bore tb as well. I'd like to know for myself how much horses i could get out of the head. I'm only shooting for mid 13's to low 14's.

you'll prolly drop about a half second or so in the 1/4
unsure about hp... who cares tho i just dynoed at 135hp at the wheels and recently ran a 14.3 (even tho I lost m #3 cylinder before the finish)
Yeah i think ill go charger next summer and then hopefully i can get the patriot stage 2 head w/o cams and have a set of blower cams thrown on and have a nice flowing engine whata think?

i may be interisted in these
has you patriot head been good to you?I have read on the org that some have had problems with them? i know this might seem stupid but the GM book says that the stock head with valve spring is all you need. So why would you need patriot head? Im not questioning you, im just tryinng to figure this out.
No one on the .org has had any trouble with the Patriot heads that I, or they, have been made aware of. All the problems you've read about on here are from the V8 world.
I used to race cars, now I race myself.

there was the one guy with MAJOR cracking throughout the head, it was a patriot head but the problem was not anythgin patriot did, they do have a good track record thus far with the eco's
I was wondering if anyone knows the hp gain of the patriot head still? Theres a guy selling one on eco forum and i was interested in it if it'd get me gains. I know the one on jbp which has adjustable cam gears and pistons and all that good stuff gives 35 hp and i was thinking the patriot head would also give about 35 because a lot of the things in the jbp build are just supporting mods, correct?
Would it be a waste to get a head when i was just running with a catback, header and a lower motor mount, performance wise.
I'd be definitely looking into the intake and 62mm straight through tb as well to have a nice flowing engine inside and out. The guy with the patriot head also has a 62mm straight through tb in which i would purchase along with the head.
Any ideas, thoughts, suggestions? Would i notice gains, or would it be a waste? I know a supercharger gives 55 horsepower on the ecotec bringing the horses up to 200 so if i could get a head, which is cheaper than the supercharger to give me 35 horses it'd bring it up to 180 horses which would definitely be worth it for the price differences.
Along with the head and the 62mm tb the guy is selling lzm stage 2 cams in which i would purchase to complete the engine setup as i planned to down the road anyways, but this way i'd finish that project ahead of schedule. With the patriot head, lzm stage 2 cams, 62mm tb, k&n typhoon intake, vibrant catback exhaust, dc sport 4-1 header, and a lower motor mount.. would i notice gains?
Finally, with the head do i need to modify the computer? Also, would i have to modify the computer for the lzm stage 2 cams? Does anyone have any idea as to where i could get more info on the cams.
I'm thinking i'd see near 35 horsepower with the head, cams and tb from the eco forum part out but i'm not sure. I know it'd be a lot less expensive than the supercharger and if i'd lose 20 hp but save 2,000 dollars it'd definitely be worth it imo. I only planned on hitting the mid 13's to low 14's.
Any thoughts, ideas, and suggestions are welcome. Thanks in advance. Sorry for any repetition in the post, I hate posting more than once so i made sure i covered everything. Thanks.

A good flowing head is an investment in the future output of your motor. It's like an intake....it's gains are magnified the more you do, just like all breathing mods really.

so pretty much with my car with intake tb header catback and some cams it wouldnt be worth it? Now if i'd supercharge then head it it'd be worth it?

The head is always worth it for the simple fact that it adds to the gains of everything else.
Example:
Say your intake gives you 5HP and your exhaust gives you 5HP you have a gain of 10HP.
Say you bolt on the head on a 100% stock motor and it gives you a 15HP gain.
Now put that intake and exhaust on that head and you won't have a 25HP gain, but probably something like a 35HP gain.
That's just an example and the numbers are nowhere near right but it's good enough for this point. LOL.
Breathing mods add up upon each other. The better the engine breathes, the better all future mods will help the car and respond to each other. Your supercharger will definitely perform better on a ported head, especially if it's ported too.
