A friend of a guy I know has a z06, I think it's an '03, and he's putting new heads, cam, etc on it and wants to sell his used ls6 heads, cam, and intake for about $1000...

The zo6 has a little under 8k miles on it, so the parts are farily new...does this sound like a good deal to you? I think I'd use the heads and intake, but get a bigger cam. I'm not comfortable changing the heads myself--any ideas (ballpark) what someone would charge to install all these goodies?

 

considering that the heads alone are worth about $1000.00 yes it is a good deal.
installation will vary from place to place but figure about $800.00 or so for time and material for a shop to install the heads and cam.

 

Thats a great deal on those parts. The heads are worth $1000, the intake $250, and the cam $150 IMO.

 

Thanks for the replies...I think I'm going to buy the parts.

Hey Demon SS, does ForceFed do installs? I'm close by (lexington), and you were recommended by someone when I was looking to do heads/cam earlier in the summer. I'm thinking about doing headers/heads/cam all at once so I just have to get it all tuned once...

 

Installation isn't that bad either, check out www.ls1howto.com , they have detailed instructions and a parts list.

 

yes we sure do do installs, give us a call at 502-648-1093 and talk to Brad to schedule the appointment. plus we can check out the heads and make sure everything is good to go, maybe even port them out a bit if you want
give you a good price on a package deal.

 

Hey Scott,

It's interesting that you mentioned head porting--I was talking with someone today that says the $1k might be better spent just getting my ls1 heads ported...what do you think about that?

I'd be getting the ls6 intake, and the heads for $1k, so figure the intake is $200 of that...so the heads are about $800. Surely my LS1 can be ported to be better than (or at least equal to) stock ls6 heads, right? I guess the question is how much $$$...

and, if I put a big cam in at the same time the springs would have to be upgraded on either head, correct? So that's a wash between the two...

If my thinking on the above stuff is correct, I think I may just work with what I've got, and put the $1k to getting some headers, a more aggressive cam, and ported. Your thoughts?

 

I would recommend the LS6 head. Strictly because it flows really nice in its stock form, has higher compression, and because you really wont get a great porting job done on your LS1 heads for 800 bucks. Hand porting is very expensive, and its almost better to go with a CNC port job because of its greater chance of accuracy. By the way, most places charge 1200 for LS6 cores, so you are getting a damn good deal on those heads. AND, if you ever want to make your motor serious in the future, you have a great starting point for your head porting.

Also, you should consider possibly just going with a more aggressive cam than the LS6 cam/heads. My cam did 409 on stock heads, and it is extremely driveable, feels just like stock and has a great idle. You wont make close to that on your LS6 heads and cam, just something to consider, it all depends on what you want.

 

Agreed, LS6 head is a very versatile piece. I use them. And I will be reporting my stage IIR's into a stage III this winter when I build my 427 unless I can get my hands on a new set of ls-6 heads for a reasonable price.

 

kind of a tough question as it depends on a lot of things, but figure a rocking stage 2 heads and cam package from us will cost you about $1850.00ish(bolts and gaskest and pushrods included), install $600-700, dyno tuning $450.00 for a total of $3000.00 sell your stock heads for $200.00ish, total cost is $2800.00 or so

buy the LS6 heads for $1000.00, with the LS6 intake and cam. for $2200.00 we'll port the LS6 heads to a stage 1 level and clean, resurface and assemble them with Patriot Dual springs, upgraded the valves to 2.02/1.57 and add bronze guides, design a custom cam and install it all with new hardened pushrods, gm bolts and gaskets, etc. Dyno tuning $450.00 total $3650.00
sell your stock heads for about $200.00, the LS6 cam for say $75.00 or so and your down to $3375.00. for $500-600 more you now have a killer LS6 heads and cam setup.
me I would go the way of the LS6 heads.
