Mopar dosent care about anything except the SS/AH Hemis and the new "Paper Cars".

Actually Terry,

They made two versions. One was a stock replacement with the 2.08 valve the other was with the 2.14 like an upgrade head. We ordered a set from Chrysler and got them straight away. This was about a year ago. They were 100% better for porting than the stock castings. They flow 30 more cfm with a smaller valve than my Hi-Po Pontiac heads or Stacy's 428 heads. Of course they got good cc numbers from the NHRA cc fairy and we didnt.

This puppy made huge power, but Grand-Pa Ron is hugely scared of it. He has gone from 10.70 in the spring to 10.10 last weekend. About a 1.45 60 foot. Come on Grandpa put your foot into it!
