These heads were taken off a 91 3.0L 300ZXTT w/ an automatic transmission and rebuilt last spring w/ new lifters and springs. 3 angle valve job performed on each head. Total cost was about $600 including parts and labor. Cams and sprockets will be included. As mentioned, cams are from automatic transmission stock but are interchangeable with cams from a manual transmission car. Basically exactly the same. Heads were resurfaced during last rebuilt as well to get a clean, smooth surface. Everything you see you get and all you need is valve covers to complete them. Ready to install. NO head gaskets will be included. You can purchase those from Courtesy Nissan online or any other Nissan source. Ebay also has them very well priced just visit PartsDinosaur.
Only defects i've noticed is that the shop that reapplied the sprockets to the inner intake cams didn't line up the guide pin very well at first and smashed it down a bit on each one. I pulled them off however before installing heads and lined them up appropriately and drove car for all summer. Ran awesome! The intake sprockets are tightened down to 90lbs of torque so extremely doubtful will turn on shaft but safety sake says you may want to drill out the pins and apply new. Cost = .50cents + time and a drill.
Since the rebuild, these heads have less than 7500 miles on them. Reason for selling? Rod knock in block made me have to disassemble before got worse and found out my crank was nearly smoked due to improper bearing installation. Whoops. No time or money to get a new crank or rods so parting everything out. Don't ask about the rest of the block, its already spoken for. Please email with any questions. Heads are currently listed on ebay - Item # 8027719802. Will end auction early for high enough offer.
