440 source

I bought 440 Source full CNC ported. I heard that the valves are OK but the springs, retainers and locks are not to be trusted. I went with COMP springs, retainers and locks. I also brought them to a good local engine builder and had him check them out and mill .050" to bring the chambers down below 75cc. He did not flow bench them but did comment that the porting job (done by Modern cylinder head) looked very good. The main reason I opted for them over Eddy's or Indy's is the stock appearance of the Stealth's if Eddy's could be had like that I'd have bought them. I painted mine Hemi orange along with the motor and it looks like it has regular iron heads, a huge plus in my book. I got it running but no real testing done yet due to transmission issues.
