ok well i have the oppurtunity to get LS6 heads for around 100 bucks that came off of a 04 GTO, she upgraded to patriot heads. well install on heads and a cam is outragious and would cost me close to $1000 dollars to install both at the shop i go to, now my question is me and a friend know how to work on cars and we are currently putting a 305 together and installing it into a S-10 and he has a 350 ready to go into his Iroc we are redoing. now i am wanting to install heads and a cam on my car, is it really all that difficult or is it pretty easy as long as you double check and tighten everything to specs, b/c i love working on my car and cant see forking out that kind of money when i could do it myself with my friend. i will have the LS6 heads ported and i am gonna go with the MS3 cam which i was told by Zach at texas-speed is a perfect combo and match up perfectly. who here did there own head/cam install and how long did it take along with any problems i might run into, now this will be my summer project as i am in school right now and this is my DD so cant afford to not have a car.

 

oh and i just recently this past december put pacsetter headers and plugs along with tearing all that EGR and AIR crap out, it went smoothly and didnt run into any problems so i am thinking it will be like that only more work and more **** to take off. and what are some of the best lifters for any head and cam application??

 

I will always tell people to do it themselves. I did mine myself as well. All 3 cams.
I would say comp "r" or Morels as far as lifters go.

 

You will be just fine. Just take your time and get a nice cold 18 pack. that is the number one tool you will need.

 

lol yeah that would help, the only thing i dont get about the whole write up on the heads and cam swap is the tightening of the head bolts, you tighten them and then you go back again a second time to tighten them again thats what i dont get. and isnt there 15 bolts on each head thats alot of going back and retightening, but better to do it then not do it.

 

I think the reason you go back and tighten the a 2nd and 3rd time is because they're torque to yeild bolts.

 

I hate to be the one to give you the bad news, but the 04 GTO came with a regular old LS1 engine, which means it has 241 cast LS1 heads, not LS6. Only the 2005+ GTO's that came with the LS2 motors had the 243 cast LS6 heads. If youre going to have them ported anyway, It's still a fine upgrade.

your right its an 05. hell with just a cam and exhaust she put down somewhere over 400 HP this girl knows her cars to and she can drive lol.

 

Ive worked on many cars, and in my opinion my LS1 was really easy. once you get the coil packs off and make urself a little room in the engine bay, its really simple.
