Does anyone have any experience with the 2200 patriot performance head? The flow numbers look pretty good but i'm curious about real world experience with this head.
Also the site lists all the way to .450 lift, I'm wanting a good cam profile with good lift and duration numbers and want to make sure the valves springs dont bind with say .350" of lift.

We found out it's not for the 2200...it's for the 2.2 OHV 95-97 motors.

Yeah, but if you ask gun he can get one for the 2200 for ya, same price, except you might need to block off the EGR, I dunno, i have one and it has a mystery exhaust port by the intake mani that i had on my other head with no problems, but im assuming it was blocked internally.
where can I get this head u speak of?
You can get this head from me. I sold 2 already, one 2200 and one 2.2OHV. Both are being made as we speak and should have results within the month.
Word of warning though...Patriot is so backed up right now that there is a 3-4 week lead time on ALL orders.
Shoot me an email to

The stock 2200 head can handle upto .480" lift. I don't see why you cant go up to that amount of lift with the Patriot Perfomance Head. Crane Cams can regrind a core cam for you and you could do that cheaper than buying any marketed propietary grind(i.e. JBP). Some grinds may require you use a 1.5 ratio rocker to stay under the .480" limit, this may sound backwards, but the cam would develop the addtional lift, not the rocker. The lift limit is in the head and valve train assemblies not the camshaft, so you can safly use a cam with more lobe lift.
I figured i'd just go for a regrind, then i can kind of specify what i want or what i'm looking for in a cam profile without to much hassle, good to know the stock head can take .480" of lift i may just have the stock head ported and polished by a local engine builder i know, save some cash and have him rebuild it the way i want. My goal is a strong Na motor with lower compression probably around 8:1 or 9:1 max that i can get around 150 to 170 hp at the flywheel and safely add nitrous or boost later on as budget allows.
One thing i am in need of thats semi on topic is a set of pistons for a 2200, do any aftermarket companies make good quality low weight pistons for these engines?

I would HIGHLY suggest deciding whether you want boost or nitrous before you go buying low compression pistons...most people go custom with aftermarket pistons, but you can buy some from Karo at carcustoms.net or jtuners if needed.

I know that places like Wiseco and JE will custom make you pistons from your stock ones. Not always cheap though.

Good to know, anybody know what that runs? i hate bugging companies till i have the cash in hand.

I paid about $650 for pistons shipped from Ross with total seal rings, pins, and locks.

Thats not to bad from what i've seen, was that a custom set or do they actually make pistons for the 2200s?
Custom set, based off the info they got from chris kelchner way back when. They can alter them to your needs once they have the dimensions.
I just checked and they were $620, job #79566D. They were supposed to be .040" over, but they measure out to .030" over. I was told by Chris they were 9.0:1 compression, but looking at them, they will be considerably more. Does anyone know how far below the block deck the piston top is on a stock engine? These look to come up about 1/16" more, they have less than half the amount of dish, wider edges, and extended skirts.
Oh boy, I'm starting to worry about interference now with .500" lift...but my NA power should be pretty darn good

Lol sounds like an interesting little situation you have there. I'm wanting to run something similar around a 9:1 piston that will handle nitrous and boost. My plans were to run the car 9:1, have some P&P work done to the stock head, replace the valvetrain with new parts and Stainless valves so that if i decide to use nitrous the engine is built right to take it, and when/if i add boost i'll switch the head gasket out for a thicker gasket and lower the compression down a bit so its boost friendly.
I do have a question for some of you guys that have played around with this stuff more than i have, The max lift on a stock head is .480 right? How much can the factory lifters tolerate before you start running into problems? also does anyone make pushrods for the 2200s or is it a custom order kind of thing? Crane makes roller rockers correct?
thanks in advance

The 2200 has a max lift of ~.480 correct, the 2.2L can take a little more. The lifters don't care about lift. They are based on lift rates and spring pressures...you shouldn't have a problem. But, if you think you need to do something about them, check out the lifter thread and look into the LT1 plunger spring swap.
2200 rockers and pushrods from Crane can be purchased from howell automotive at good prices. Or, check the rocker post for info on getting the Proform (or others) rockers.
