curious to see if gm would sell there P&P head w/ the car as an upgrade? hmmm, also RSM Racing i believe has a cylinder head, i'll try to get details if they do have one.

 

If i do go with the SS. A Ported head and Header will be one of my first mods.

 

wow I didn't know patriot sold ecotec stuff I know about their gen III goodies. if they profrm like the gen III heads they should yeild some extra ponies

I haven't hear good things about RSM but I had a friend order from Mantapart performance a couple times and said they where very helpful

 

rsm has improved over the years, the things u probably heard bad about them was shipping, that was because recently they had moved which caused a back order, then sema came up and more backorders they are working dilegently to get stuff together and shipped out. i'd trust them over mantapart any day of the week and twice on sunday. as far as patriot performance i now from reading on LS1 forums that their heads are over priced for how much they flow. but thats just what i read. if rsm's ecotec head performs n e thing like there 2.4 ld9 head expect around a 20whp increase from the head. and thats n/a.

 

I just got a reply from Patriot. Say there head can only be used on the 2.2L. Why? I have no idea

 

interesting only main difference between the 2.2 and 2.0 is the internals, everything else is the same.

 

patriot has the cheapest gen III heads on the market whith the right valvetrain they can produce lots of horespower who else can give you 500+hp for a just $2600 most gen II heads cost that much

maybe the reason the 2.2 head want fit the 2.0 is cause of the bore is to big like 350 heads want work on a 305 thats the only thing I can think of

 

Isn't the supercharged 2L Eco just Destroked with the Same Bore as the 2.2L?
