VAC's Stage 3 Performance Cylinder Heads:
Unmatched Performance
VAC's Stage 3 Performance Cylinder Heads are the ULTIMATE in
cylinder head technology and performance, crafted with more than
50+ years experience in the racing field.
While we are know for late model BMW heads capable of making 155
HP per liter N/A, we have stayed with both the cutting edge trends
on the S65 and have been in development of heads for both N/A race
performance, street performance, and Forced induction.
When people say "it cam be improved" our track record says
otherwise and our results are undisputed. 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 our heads have been 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!

3 heads for use on the ultimate street performance vehicle as
well.
