Hey guys!

So im trying to decide what to get head wise. I have my 01 stock heads 706. No they arent leaking no coolant loss nothing. Im trying to find out some info on these heads so i can save some money.

Would my 706 heads be Notched like the 853s? Ive heard that earlier 862 heads have the notch but found nothing o 706. I ask because i already have head gaskets MLS of course and dont wanna use the crappy other gaskets. Also there is a year differnce with those gaskets with 99-01 and 02-06... i was planning on buying a set of 04 706 heads but i can save some money with pulling mine and using a machine shop to do a valve job and freshen up the heads. Any info would help!

 

706 heads do not have a notch....its the 862 heads

 

Are the the castech 706 heads? If they are, probably not worth the time and money to use them, if they arent castech you should be fine using your heads!

 

The ones the i was going to buy are castech heads. Mine im not sure but the miles i have on them i should be good getting them to a machine shop.. but if i should be good for my parts then perfect!

 

Pull valve cover and rocker stands and look for the little battery looking casting mark...

 

Like this.

 

Thanks man, I had a pic similar to that link and couldnt find it...

 

Well i havent been able to yet but with the millage i would imagin its going to be okay. They ones the guy was going to sell me has the battery logo.
Idk why they make gaskets for 99-01 and 02-06. Maybe just a felpro thing?
