Polyquad porting for Ford Heads

Unread postby RedVert88 » Wed Jan 29, 2014 10:32 am

First of all, Iot of great info on this site. Thanks guys!

http://www.motortecmagazine.net/article.asp?AID=1&AP=1

The article above isn't new, but I just ran across it the other day and I couldnt find where anyone had tried it on a ford head. The articles Makes since of why 4v heads make power at higher rpms. It seems like from what I have read, B-heads and probably C-heads could benefit from more swirl at low rpm. Has anyone tried any of the porting tricks talked about in the article?

Excellent article - I have not heard a peep about this on any Ford forums I visit, but then again I don't go into the modular forums. It would be great to see a manufacturer or machine shop based business licence this for the 3 valve heads (and 4 for that matter) and get the cost into a more affordable range - $1,000 a hole on a V8 adds up to more than most guys would be willing to pay for the gains unless they make some serious cash for the effort.

pretty cool thought its nothing new though, we've been offsetting valve sizes and recessing seats since the 90s to give the 4 valves a little more grunt, I dont know about them claims though Id have to see it to believe it

We're more than capable of doing a set of heads here and our price on valves would be more like quarters on their dollars but i think the biggest issue would be paying them for use of their design?? I wonder if we did a set of 3 valve heads if they would be entitled to royalties?

Does anyone have a patent number I can look up?

Yeah I thought the article was really interesting. So I guess these are things machine shops have been doing on 4v stuff for a while. Vizard always does a good job of laying things out so they can be understood.

Thanks for chiming in.
