Sounds like me these days. Back when I was younger I'd spend an entire day doing nothing but stuff to the car and installing parts. I can't really do that anymore

such a silly comment, Mr B not sure if you do it just to create a disturbance or whatever I dont care much. Folks can do the math.

Fact is: GMR head went for 1000 dollars in the beginning in 2006 up to around 1500 at the end. This is what you got:
  • a completely new head
  • cnc ported exhaust to a proven profile only available to GM.
  • new valves, new springs keepers ,rockers, lifters, cams etc
  • all brand new and all complete and assembled.
the closest you can get is buy a new head and get it ported , this can be done, with very good flow numbers. maybe 500 dollars for the porting.
now price the head and all the new parts.

Right.

fact is, you cant get them anymore and thats unfortunate. but dont for the moment think it wasnt the best value in town, because it was.

I posted my mods and details on page 5 of this thread. Didn't realize it was the same thread when I made my post today. And didn't mean to get Mr B's panties in a bunch...again lol. Fact is I've quite happy with my gmr head and I got a great price on it from Powell, especially if you consider how rare they are now.

Hey guys.... I havent worked on the car since Friday.

Today after work, I'll be swaping over my supertech springs and cams from my stock head to the GMR head. After the new T-stat arrives, I'll be installing the head & timing components.

I work on her for about an hour or so each day after work. It's been a very busy year for me.

I do have a lot of nice photos that I promise Ill get posted, but for now, enjoy this pic of my clean block & pistons

it was far from the best value in town I don't care if it was all new parts in the head 1500.00 bucks for 28hp is not a good a good bargain if my math is correct that is 53.57 per hp you can make that 28 hp elsewhere and the money saved can net you more hp from somewhere else hell you can get a used tvs and make 100hp so a tvs at 1500.00 and you get 100hp that's 15 bucks per hp and that's money better spent

my panties are not in a wad but people think this head is the holy grail of unicorn sprinkles and it is if you want to build a time attack engine for your cobalt but in the real world of performance and hp vs dollar spent it is a poor choice but for a person wanting what jeff wants that's different
