Hi there is a lot of BAD info made by some on the net that really dont have a clue about these heads, I have a few sets and know a few others with these heads also.
There were two diffrent supplyers/companys of these 32V heads Dominion Performance and Arao Engineering with diffrent people invloved. Hal from Dominion never ever ripped anyone off and was selling Dominion brand parts/heads up till about mid 05 when he got sick and had just past away recently last year, his friend also got the last two sets/pair of 32V dominions heads recently. Most dont realize the Dominion version heads were cheaper to buy as Hal work from out of his home based buisness and did have his own web site in the past.
The other company in a diffrent cali location also made there own Arao 32V version heads. Arao has had some problems in the past with getting componets made/cast for there 32v version heads which is why prices were higher in the past. I know about the guy that spamed all the auto forums about getting ripped off and then suddenly dissapered, there were component problems but he did not get ripped off and did get his ONE OFF custom heads that no one else has. I posted about this on pg3-4 in the above gt40 link.
Anyway my Dominion ford version 32v heads cost $4000 new. The other Arao ford version 32v heads are $6500 new. I know that neither one of these guys/supplyers were getting rich making these custom heads as they are a pile of work to make.
