used Loyning prepared aluminum head (04-461)

used top-of-the-line Loyning prepared aluminum cylinder head assembly (04-461) for sale. cylinder head assembly includes valves, springs, retainers, billet aluminum rocker stands, ARP studs for the rocker stands, and a Loyning prepared rocker shaft assembly. the cylinder head has made 120+ HPc when equipped with one of my 4:1 exhausts since it was purchased in 2005 (ie: back in the 3.189" OD forged aluminum piston days). as strong as the head is, it wasn't strong enough to drag either of my 4:2:1 exhausts or an asymmetric 4:2:1 exhaust kicking and screaming up to 120HPc during exhaust testing last August!! the head has only been used on the dyno so has never been subjected to over-rev's, over heating, or anything less than professional installation, adjustment, and care. $4000 plus shipping from 93555. the cylinder head as above, its intake manifold, and its Weber (up-dated by Arnie after exhaust testing in August 2015) would be $5000 plus shipping from 93555. flow test data from multiple tests will be made available to the buyer for purchase after the head is sold.
