Freshly refurbished and machined 317 aluminium cathedral-port cylinder heads. These came stock on 2001 and newer 6.0L truck engines (such as the LQ4 and LQ9). They share the same internal port layout and flow characteristics as the popular LS6 (243/799) heads.
Machined and rebuilt by our engine machine shop in Myaree, Western Australia – Southside Engine Centre.
