HG Rebuild important parts list - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

When building a motor with a blown head gasket, what does Zilvia think about the necessity of replacing the rod bearings and main bearings as well as rings. I hear that that milk shake you get with a blown head gasket can cause your bearings to have premature failure after just replacing the HG and head bolts.

At this point I was planning to replace the following:
Head Gasket (apexi)
Head Bolts (ARP)
Main & Rod bearings (Probably ACL)
Rings
And I was planning to deck the head. whats the likelihood of the block needing to be decked upon typical HG failure?

That deck has got to be clean. But it's not like everyone who replaces a HG gets the block resurfaced so it's posible. Just make sure it's super clean and take your time.
