Starting with Edelbrock's new LS-R casting, the RFD "LS-R" produces enough flow to support over 1,000 hp. Large LS-based engines of 480" or more need a cylinder head to supply it . . . and the LS-R is it! This head is designed to maximize the potential of GM's race oriented LSX block, taking the generation 3 & 4 engines to a whole new level.
The true canted valve design offers the most port flow and combustion efficiency possible with a two-valve design. The head uses the GM SB2 valve cover footprint required by the added width of the canted valve layout.
This is the most powerful LS-based cylinder head available today!
