Just need a confirm from the community that rockers, lash adjusters and valves are interchangeable throughout ecotec variants. I am planning on buying a brand new lnf head and using those listed parts in my LE5 ported head. IIRC the valves are upgrades, with the exhausts being sodium filled and the gm performance build book calls for le5/l61 valves to be replaced at 300hp and lists lsj/lnf valves as possible replacements.

LNF heads are going dirt cheap brand new, makes more sense to pay a couple hundred for a complete kit than say $300 for aftermarket valves alone. Then add rockers and adjusters at $10+ a pop online and it gets expensive fast.

 

LNF has direct injection, not sure the heads will work for you properly. Maybe lsj heads will work better.

Ooooor are you going to just buy a new lnf head and strip the valves, adjusters and springs? I may not be reading your plan right. But it seems like you are planing on one of the two things.

 

Gonna strip it down, it is the head internals I'm interested in. Valves, adjusters and rockers in particular.

 

The head you're buying may not be complete with valves etc.

Check into that before you're stuck with a bare cylinder head.

 

Head is brand new and complete, even has cams.

 

Anyone have an answer to this?
