i dont have the cnc victor jr...would of love to try but were not out when i built...always curious to think what it would could of done...and jeez racemart has cnc victor jr for 821.00$ per head..one day:) but i cant complain...my head port alignment was so unbelievably perfect. i took a imaging camera to each one and every port cause i was so amazed that everything was so money on..what i think made my motor shine was the valvetrain...i have barton rollers rockers along those new ultra lightweight elite solid roller lifters with pushrod oiling....but overall its a very gentle true street combo being ultra light weight..475lbs i just fired it off last week..so need this snow to melt cause im dying to play
