Default ls7/zo6 Heads

My zo6 Tends to smoke a little more than Im comfortable with, the Guides must be worn out?
Valve Seats worn too?

How Much should It cost to Get this issue fixed if I dropped the heads off at a shop?

I would stop driving the car NOW b/f you drop a valve or have some type of catastophic failure, and contact Carlos at Vette Air to send you your old heads for the new LS7 heads that he just started to recently offer, that have all the upgrade for power and more importantly reliablity! I belive it will only cost you around $1,595 (plus your stock heads).

See the below post for the heads I am referencing and look at posts #15 and 16 to see exactly what he does to fortify these great LS7 heads:

You can also contact Richard at West Coast Cylinder Head and do the same thing with him also. Good luck!

That price seems about right. That's roughly what I'm paying to get the guides swapped out (and to R&R the heads). My car was smoking a bit, too, and it turned out to have another broken valve seal. This is the second time I've had to replace seals. Not sure what's going on, but hopefully this will be the last time it happens.

I would expect $500-700 to R&R the heads. Then ~$600 just to do new guides, clean them up, and valve job. While they are off I would just get them decked/ported and get some power too.

Should we assume you have the heads off, disassembled them, and checked for valve stem wear as well as the guides or are you just guessing cuz your good like that?

So you didn't pull the heads therefore you can't properly assess their condition? Car runs great?


No, I'm afraid you're not good like that...

The Car does run Great... Just Smokes a lil

The heads are the Problem... what else needs to be assed on their condition? Its not like im just going to Change the Guides... once the heads are off they will be Ported/Polished, New valves, guides, seals... everything.

Oil in the combustion chamber can come from more places than the guides..... Which was why I originally asked you why you came to the conclusion it was heads. If you are smoking beyond initial start up, then the intake guide seals may not be the problem, and most likely are not the problem.
