Just wondering if the CNC chamber option is worth it. I'll be getting a set of Trickflow 23 degree heads for my new 355 motor and was wondering if the 4 extra cfm on the intake and 9-10 extra cfm on the exhaust is really worth the extra $175.

The heads that will handle .520 of lift are $970, or $1,145 for the CNC version. If I step up to larger diameter valve springs, I'm in the price range of AFR's and would rather get those.

 

Geez guys!

Nobody has CNC aluminum heads??? I know a bunch of you guys are head wizards so let me know!!!!!

 

CNC macking is a computer making all chambers exactly the same. this will help to keep all the cylinders balanced. meaning having the exact same compression, swirl, burn pattern, etc.... it's like balancing and blueprinting a motor, not necessary. but, if you want maximum power you do it.

hand porting you may end up with one chamber at say 66cc and another one at 64cc and so on.

 

I orderered these heads last night ( CNC ones), and I'm really excited about it. I also oredered the collest aftermarket valve covers ever!!!! well, that match my heads anyway. I also went with a ARP bolt kit as well. NO shortcuts here!!!!
