JM Cylinder Heads (Strikers, ported o.e.m., Hemi, SRT-4, etc) is currently up for sale. All the programs for making the hardware still exists.
But until it is sold, all existing inventory is on hold.
Sorry '68, I should have said The GEN IV heads which are the 2008 and newer factory Viper heads. There is (again) a conversion program underway to adapt them to the Gen IIIs. They are an excellent head and are what gives the Gen IVs the lion's share of the additional 100 horsepower over what the Gen IIIs make.
I'll post up when the Striker's and the ported o.e.m. heads are available again.
