heads, and of course drastically more when used with forced
induction. We have spent many, many years on the dyno, the flow
bench, and even more years though world-wide racing experience to
achieve such excellent results while being reliable enough to
compete in professional motorsports. Our Stage 3 heads are intended
to produce maximum peak horsepower while still maintaining
excellent powerband, the crucial secret of the fastest race engines
in the world!
Even though they are an extreme departure from stock, we have stage
