High-Tech Tightening – Fasteners take their rightful place of importance
When you build your engines, you put measured thought into every component you use. From the intake system to the exhaust manifold, everything has its place and nothing is installed without careful consideration. But what about the fasteners? Some of the most critical components are held together with relatively low-cost fasteners including screws, nuts and
Cylinder Head Design & Selection
Choosing the “right” cylinder heads for an engine build can make all the difference in an engine that delivers and one that falls short of its potential. Horsepower, torque and throttle response all depend on how well the cylinder heads, camshaft and induction system work together. Choose the right combination and you’ll build a winner.
Flow Bench Testing is More Than CFM Numbers – What You Need to Know
On the surface, flow bench testing seems easy, but it’s not. Many in the industry have become solely fixated on cubic feet per minute (cfm) numbers, placing importance on a number that is easily manipulated and ignoring other data about a cylinder head’s performance. This thinking would make flow bench testing seem easy, but this
Head & Block RESURFACING EQUIPMENT
Regardless of what type of engine work you do in your shop (stock, performance, diesel, marine or anything that comes in the door), you need the ability to surface heads and blocks. Deck surfaces on high mileage heads and blocks are often corroded, pitted, scratched and/or out-of-flat – especially if the engine blew a head
The Lost Art and Business of Head Porting
If I had my current shop rate paid to me in a lump sum for every hour I spent porting and flowing heads and intakes in the ’70s and ’80s, I could build a new race car. In ’76 when I started running Pro Stock, my wife Linda got me a SuperFlow 110 for Christmas

Whether you are a seasoned veteran in the engine wars or finalizing the specs for your first ever build, it is virtually impossible to avoid it. The flip side of that coin always carries another word
Cylinder Head Design, Selection for Engine Builds
Choosing the “right” cylinder heads for an engine build can make all the difference in an engine that delivers and one that falls short of its potential.

Don’t Gamble When Choosing Cylinder Heads
A cylinder head is much more than a casting that tops off the block, holds the valves and forms the combustion chambers. The head works in combination with the camshaft, induction and exhaust systems to determine how the engine breathes, the engine’s power curve and personality. The “right” cylinder head on an engine will deliver
