Cylinder Head Porting Services by Randy Brzezinski

"UnderCover Porting"

Our "UnderCover Porting" adds 15-30 horsepower to your engine combination by modifying the critical areas of the head which increases the port size only by 3-5 cc's while retaining a stock-looking port. View the various UnderCover vs. Stock port flow figures comparison chart.

Acid Porting

Acid Porting uses chemical treatments to enlarge the intake ports by 8 to 14 cc's, which maximizes air flow & increases intake volume, providing excellent gains in engine horsepower.

CNC Sportsman Porting

Our CNC Sportsman ported heads have a more developed and larger intake ports. Valve guides are honed to the proper clearance for your application and seats are machined to the final size.

S.S.T Porting

Our "SST Porting" includes CNC machined intake port openings, intake bowls, exhaust bowls and combustion chambers. The heads are flow tested and a flow data sheet is supplied with each set of heads.

Disguise Work

When it comes to modifying racing cylinder heads, Brzezinski Racing can maximize horsepower without altering the outside appearance of a head and/or change the casting numbers.
