First I would like you all to see this link for ideas. http://460ford.com/viewtopic.php?t=18321
(yes the site is back up as of today anyway)
I would like to base this on rated flow as that reflects the likely potential vs being subjective to who has tested more and whose valve job etc..
I think summary first list and details follow summary.
Head must be readily available anyone can buy and expect delivery in a week or two. CnC package ok but no one off customized to someones specific application. It is fine to note in details highest factual known hp number acheived to date but not speculated hp. Also ok to state that flow numbers beyond x have been acheived with additional work as long as you have factual numbers. Cost will be included and not ranked just info. Will also state costs of support pieces required and based on a start from scratch basis vs what you may already own.
