Hey all!!! I tried to search but Iʻm not coming up with the exact answers I'm looking for... Iʻm going to be port and polishing my stock 799ʻs on my ʻ11 Tahoe to match my cam upgrade. I am wanting to find a part number to the GM or Felpro gaskets that I will need to replace... Also I have to put on the 241 heads I bought while my 799ʻs get worked on... Will these gaskets be comparable for both sets of these heads? Sorry if this is redundant or confusing... Thanks in advance!!!

 

Not sure which engine you have but I believe these are what you need. If you can, verify with a dealer first for your engine.

12589226 head gasket should cover both the 4.8 and 5.3 engine's with and without DOD.

89017690 Should be the valve cover gasket if there actually bad....

12617944 Exhaust manifold to head gasket.

12577215 Valve cover bolts with rubber grommets

 

Thanks for the info!!! It's the LMG engine...

 

i would p&p the 241s then make only one swap. same heads.

 

my bad i was thinking 243.

 

K thanks
