I have had some personal PM's and emails because of my post and some have been in touch with Jason at ProMaxx. If they want to step into the conversation they can provide more info. This is a part of one of the PM's.


""We have multiple spring options. Cnc heads are 185cc runner looking at $1400 loaded for as cast, and $1900 loaded for cnc ported.


I also have flow charts but like I said they were from private PM's so I don't feel at ease posting them. If in dought call and ask for Jason at ProMaxx. They are kinda out of my price range right now and my next purchase will probably be a set of W7's for an R block I bought and a set of the new Victor heads.

Here's a link to my old post.
