The Cometic 0.040 head gasket...
The Cometic 0.040 head gasket is shown in place just prior to mounting the passenger side head. Note the use of ARP studs-highly recommended at this power level.
The Comp Cams custom grind...
The Comp Cams custom grind solid roller cam features 265/272-degrees duration at 0.050 and 0.691/0.691-inch lift. Crower roller lifters are employed and, though the Comp Cams valvesprings have an open pressure of 620 pounds, Kevin feels that a lifter bore brace isn't needed with this camshaft profile but a KRE stud girdle certainly is needed to maintain the proper valvetrain geometry by preventing stud deflection. Kevin says, "These CNC-machined 6061 T-6 aluminum systems are lightweight, durable, and easy to install." Beneath it are Scorpion 1.6:1 roller rockers.

Once the other stud girdle is installed, the KRE valley pan goes on using silicone to seal it.
