emagdnim Posted January 27, 2008 Author Report Share Posted January 27, 2008 Which numbers are what here? The bottom numbers below the lift are the CFM numbers. Link to comment Share on other sites More sharing options...
Maxzillian Posted January 27, 2008 Report Share Posted January 27, 2008 Which numbers are what here? The bottom numbers below the lift are the CFM numbers. Which numbers? I see some that qualify for flow, some that look like extra valve lift numbers, horsepower, and percentage. What is what? This is great data and all, but none of it makes sense. :?

Technology Posted January 30, 2008 Report Share Posted January 30, 2008 This is good stuff. Is there more information about "thin" OS stainless valves? Are they lighter than stock? Link to comment Share on other sites More sharing options...
tsiconquest88 Posted January 31, 2008 Report Share Posted January 31, 2008 good info for sure but its going to vary cus what was the extent of the port and polish job? besides different places do better work than others so where u had urs done might not be as good as say someone that know exactly what to do with these heads, not for nothing but who *DM uses, or even some other guys here. cus anyone can port and polish but to get the best job done as to what is known to do with these heads is better. not tryin to bash here just so u know!!! just tryin to get added info for these numbers and shed a little light. did it have bowl work or just intake and ex ports? etc Link to comment Share on other sites More sharing options...
jszucs Posted January 31, 2008 Report Share Posted January 31, 2008 This is good stuff. Is there more information about "thin" OS stainless valves? Are they lighter than stock? I had a set custom made by faria SP if your intrested in them you could ask dad (Randy) he worked out all the details with them and they don't deal with the public so Im sure he could get you a set ordered. They came in at about 400 bucks however. Link to comment Share on other sites More sharing options...
Indiana Posted February 1, 2008 Report Share Posted February 1, 2008 This is good stuff. Is there more information about "thin" OS stainless valves? Are they lighter than stock?ya this is the huge benefit from using them not that they are "OS" as soon as the seal at the seat is broken the OS valve lets air flow in sooner because of the shape of its back and at full lift it lets in more air because the gap is so much larger http://www.b2600turbo.com/images/IM008111.JPG watch this avi file: www.b2600turbo.com/IM000496.AVI both valves are open the same amount, you can see its obvious which allows more flow.
