and have read a bunch of threads dealing with the issue. I want to replace both of the heads with non-Castech heads and have been searching for a while but all re-manufactured heads I have found are Castech (since there are so many bad ones). Does anyone know where I can find non-Castech re-manufactured heads?
Also, this is my parts list so far. Any additions?:
#89017252 5.3L/4.8L Complete Head gasket kit
#12498545 Head Bolt kit
New exhaust manifold collector(?) gaskets
I also wanted to replace the bolts that hold the exhaust manifolds on since they seem to break. Should I do this? Any recommendations?
My truck is in pieces and I need to get this resolved quickly. Worst case is to get one re-manufactured Castech head and put it back together but I would really like a long term solution to the problem. Any other ideas? Thanks everyone!
Unfortunately, I am in the EXACT same position you are. I have my bros truck down to the shortblock due to two cracked castech heads. I picked up a set of rebuilt 862s. While I am not going to try to defer you from buying new gaskets becuase it is a good idea, Ive never once replaced intake manifold or exhaust manifold gaskets when Ive had one apart. I dont plan to this time around either. I just ordered a head gasket kit, one exhuast mani bolt, two water pump gaskets, and a complete head bolt kit and it was 125 bucks shipped. (35 was for rush shipping).
I am experiencing a loss of coolant, as described in the All Data Tech.Serv bulletin #06-06-01-019B Problem for me is that this Engine was put into my truck in Nov. 2010. Started having problems about 9 months out. I do not want to use Castech at all, if they are still showing up in Re-maned engines in 2010. What the heck can I do?
So I need new head bolts, head gaskets, intake gasket, valve cover gaskets, exhaust manifold gaskets, and the collector gasket. Am I missing anything?
Yes on the new head bolts (GM or ARP) and yes on the new head gaskets (GM MLS). No on the valve cover and intake gaskets, they are reusable. The exhaust manifold gaskets sometimes can be reused. Texas Speed has a head swap gasket and bolt kit that is good.
