Head change on a L98
Does anyone know if I can put a set of older AFR 180's on a L98 without having to reprogram the computer? The heads are milled to 64 cc chambers.
I need to redo the valve stem seals on this recently acquired car to stop the smoke on startup issue and these would probably make a nice improvement over the factory heads with only a bit more work involved to swap the heads over just replacign the valve stem seals. But only if the ECM isn't going to have issues with the new heads.

Re: Head change on a L98
if its a stock L98, the added heads may work ok on the stock computer, but it will greatly benefit from custom tuning. Also, may consider running the vette eprom as they had more aggressive spark tables for their aluminum heads.
