Does anybody have a ballpark figure on how much the 99+ headswap would cost in labor? That would have a big impact on how soon I can do it. Thanks in advance....
headswap question

Joel, I think the PP? heads are $1500.00, parts. I have no idea how much a shop would charge you to install them...
Most say 50+RWHP...Cobra territory :-D

Jimbo, GR8WHITE left a link in another thread the SHM website where there was a package that included everything I needed for $1350. Not a bad deal really. Just wondering what the labor would be. Thanks for the reply!

Joel, figure the labor to get down to the heads, prep for new heads without any parts, is about 5 to 6 hours including the rebuild time.
So 6 times $60-70/hr.
Good estimate, I am doing it right now on my 87.
Good luck
Thanks Adam!
I guess that's not too bad. For the gains in horsepower I think it would be worth it. That would still be less than half of the cost of a supercharger, not including the labor for installing one of those. Paying someone to do it would probably be worth it as it would save me a lot of time and cussing if I tried to do it myself. It sounds like it would be a little more complicated than just an OHV head setup like on the 5.0.
I want that 10:5 compression baby!:rolling:

Joel, I am sure if you leave the engine work to the specialists, they will leave the cookie selling up to you:lol:
It can be a bitch if you don't know what you are doing.
If you do it, get the Fel pro lockwire gaskets, they are very strong.
:lol: :lol: :lol:
I heard that! I had a mechanic that would charge me more when I would bring it in after I tried to fix it...more than if he had done it himself...
Or......you guys can come to Illinois and we can try to figure it out together? I'm sure Steve and Zach would help too. I'll provide the beer and cookies!

Do you also have to change the intake when changing the heads?
Absolutely. The lower 99+ intake has much larger ports where it feeds the heads than the 96-98's do. The ports are actually a different shape also.:rolling:

I have another question. Will the motor and exhaust sound much different with the higher flowing heads and new cams?
I doubt the sound will change. Do the 99+ GT's sound that much different? I don't think so. Face it, You're going to have a SLEEPER!!! :beer: :thumbsup:
BIG time. :-D
