Im selling my fully built LS head. It has been thoroughly ported for street use and polished up of course too.
It has +1mm Ferrea intake and +1mm Ferrea exhaust valves in it.
Portflow bronze guides on intake and exhaust sides.
Valve seats are a 5 angle masterpiece with the Ferrea valves backcut to match the seats.
Chamber has been de-shrowded for the larger valves and to flow more CFM around them.
Crower High Pressure dual race springs are used. Part number 68182. These are the better of the 2 sets they sell.....good luck floating a valve with these suckers--Super stiff!!
Head has been shaved to ensure straightness, but only .002" so no worries about increasing CR too much.
Im including stock retainers...which I used for this setup mainly for their strength and their longevity. Also including stock LS cams.
The intake manifold exhaust heat passage running from the #4 exhaust port to the intake manifold has been blocked off to keep down IAT's.
Attached to the head is a polished aluminum Venom sheetmetal intake manifold including a hondata intake manifold gasket to keep heat transfer down. TB, sensors, rail, and injectors are not included.
Up top is a polished early style b18a/b style valvecover. Included also are NGK blue's.

All this for $1500 obo. Do the math, there is lots of money invested in this head.

Optional parts to be sold with the head package are AEM silver adjustable cam gears. OBD1 distributor missing ICM and coil. ARP head studs.

All work has been performed by a professional. He does many 6, 7, 8, 9 second race teams valve and head work. Bullish, IMPO, Jotech and more.

And the pics.....

 

Up.....gotta be sold.

 

Moving up for the people who have slow LS motors and want to be faster.
