Manufacturer profile information
Profile L182-C
A 280-degree street and strip profile for the RB26. The archived Kelford catalogue states that the head does not require cam-lobe clearance machining. Lift is listed as valve lift, without a separate net-lift designation.
| Specification | Intake | Exhaust |
|---|---|---|
| Advertised duration @ 0.35mm | 280° | 280° |
| Duration @ 1.00mm valve lift | 242° | 242° |
| Valve lift | 8.95mm | 8.90mm |
| Valve clearance | 0.25mm | 0.30mm |
| Suggested centre lines | 110° | 116° |

Manufacturer profile information
Checking heights are shown with the duration figures. Net lift is the net valve movement specified by the manufacturer, while cam lift is listed separately. IVO/IVC denote intake valve opening/closing and EVO/EVC exhaust valve opening/closing. BTDC/ATDC mean before/after top dead centre, and BBDC/ABDC before/after bottom dead centre.
Installation and profile selection
Confirm the exact engine version, valvetrain design and the modifications required by the profile. Check cam timing and valve-to-piston clearance during installation. Springs, lifters and other supporting parts mentioned with a profile are not included unless the profile explicitly states that they come with the kit.
