what year did the head design change..i had a 99, and spit a plug out..looking at a 2000 w/ 22k miles...like new...still fear the dreaded spark plug flying out..cant find what year they changed...also, chime in on that u think it may be worth...( 13800 is what i can buy it for ) thanks in advance..

 

Late 03 is when they started with the upgraded heads.
A 2000 w/22K miles on it,,,13800 is a little high but I'm sure it's well worth it.Depends on how bad ya want it but I would try to talk um down some!

You meant Late 02. My 03, built in January, has the upgraded heads.

 

I'll have to check my build date. My 03 stock motor did not have the upgraded heads.

some of the 03's had 4 thread heads. I have heard of guys with one 4 and one 8. God I would be pissed if my 03 had 4 thread heads. I did a lot of searching to get the right one but Im not gonna be taking plugs out at the dealer to count threads. BTW 4 thread heads are fine you just have to torque them to correct specs and make sure they stay tight. Guys have gone 10 sec on 4 thread heads.
