mopartsracing - Sidewinder Cylinder Heads For Big Block Mopar

I had a wonderful experience with Todd Marsh. $895.00 he also offers porting by retired Nascar porter. Tell him what cam you want to use and he gives you a discount on Isky springs. Comp's 275/285hl will get you where you want to be or 282s sft. Heads will be ready to bolt on.
