hey guys im sending my 317 heads for my turbo build to get rebuilt and im already putting patriot dual gold springs kit along with a 5 angle job,but ferrea vavles is here in south florida so i was wondering if lighter stronger vavles will improve anything?

 

The less weight in the valvetrain the better. You just gotta figure out if it's worth the cost for your application.

 

why exactly is it better?and any improvement? cost is not the problem

 

By taking weight away from your valvetrain and strengthing it at the sametime is benefical because it makes the valvetrain more stable at all RPM's i.e. reduced flexing, extending the life of the components. Lightning different components (retainers, locks, valves etc..) will reduce the amount of strain you put on the spring, allowing them to control the valves better. You will be able to bring the motor into higher RPM's if you need to because of the now stronger and lighter components.

 

thanks alot guys

 

The valves in my Dart heads were made by Eaton and were larger than stock, but also lighter than stock. The also had a "REV" part number on them.

 

longer?how did that work out?i know u can shim the spring seat for shorter springs but longer vavle stem?

 

Larger, not longer. The guide can be machined to accomodate that. Longer than stock would mess up the valvetrain geometry big time.

 

ohh that u can do

 

Sorry, just to be clear the Dart valve was 2.02 and 98 grams and the stock is 2.00 and 101 grams.

 

nice gain

 

guys wat are the stock size vavles for the 6.0 317 heads?

 

the lighter the valve train the better. also improves velocity and less strees on the springs and able to turn higher rpm due to less weight quicker turn up also
