Valve Guide Clearance - Your AFR Heads come with proper guide clearance (.0012'-.0016') for most applications.Please see note on guide clearance below. All MARINE Applications - We strongly recommend Inconel exhaust valves & also offer a hard anodized coating to slow the effects of corrosion.For example, 15lbs boost on a 2.125 OD valve reduces the springs closed seat pressure by approximately 40-45lbs.

We strongly recommend upgrading your valve springs or increasing your valve spring pressures since boost pressure on the valve reduces spring tension. Since boosted or nitrous oxide applications accelerate RPM quickly, additional spring pressure is required.

Boosted/Nitrous Applications - We strongly recommend considering Inconel exhaust valves and AFR's optional heavy duty intake valve for power adder applications.

Stud Girdles - Due to many available factory OEM and aftermarket style/variations your existing stud girdle may not fit (AFR heads require AFR Stud Girdles).

Mills - Flat or angle mills could affect flow numbers and might require a thicker intake gasket.

Larger pushrods will not fit without clearancing and is not recommended since some areas are very thin. Check pushrod clearance with heads placed on the block before final assembly.

Pushrods - Different length pushrods might be required, always check pushrod length.

Your block manufacturer or engine builder can recommend oil restrictions to the top end/valve train components.

High Volume/Pressure Oil Pumps - If you are using a high volume or high pressure oil pump it can submerge the valve seals in oil causing smoking or oil consumption.
