1. Intake ports are ported to create maximum velocity then rough cross hatched to provide better fuel atomization, which increases combustion efficiency providing increased power both at low and high rpm.

2. Exhaust ports are ported to relive internal pressure quickly, yet provide enough velocity to scavenge well, insuring a full fresh fuel and air charge will be delivered to the combustion chambers, not diluted down with left over spent gases from the last firing.

3. Head surface is milled them hand lapped to create a multi directional #32 micro Finish surface, this leaving hundreds of micro ridges to be crushed down by the steel gasket forming a super micro barrier for better gasket sealing.

4. Intake to head ports are purposely mismatched or stepped to fight unwanted reverberation and to reduce boundary layer effects improving port flow.

5. Valve seats we have tried 3 angles so called 5 angle, and many other valve and seat combinations, we have found that the factory angle on the valve is overall the best and that the blended radius parabolic valve seats pioneered by Gude performance provides the most horse power and longevity on most Imports.

6. Valve guides in most cases we have found that shorting the valve guide is helpful and will promote increased flow while still maintaining excellent valve control.

7. Valve springs Gude performance camshafts are designed to operate to extreme rpm on stock valve springs, we spent countless hours designing and developing profile which will not require a high pressure valve spring which can cause added friction and valve stem failure due to the high loading of stiffer springs vale stem failure will usually cause major engine damage.
A few exceptions we will up the spring pressure 8000 rpm.

8. Camshafts Gude performance Bullfrog or Stinger cams are ground to precise tolerances, and are of the famous Gude profiles. Gude poured out all 30 plus years of experience, into designing cam profiles that are stable at extreme high rpm with stock or light valve spring loading, this increasing horse power and engine reliability, as high valve spring loading can case excessive wear and result in total valve stem failure destroying a expensive engine see article on this site.

9. THROTTLE BODIES Gude throttle bodies are bored and a new oversize butterfly is installed, this providing maximum flow and performance, with Gudes 20 years of throttle bodie experience Gude has developed a unique aerodynamic shape of the throttle bodie inlet barrel this not only improves flow but also throttle response this make for a great circle track, road race, or autocross throttle bodie, as well as drag racing.
