All head studs were installed finger-tight.
Our taller-than-OE Crane roller lifters required the use of spacer washers between the block and lifter buckets.
The oiled roller lifters are inserted into the OE plastic lifter buckets. These register flat-to-flat, orienting the lifters properly for roller bearing operation at the lobes.
With all four lifters snapped into the lifter bucket, the assembly is then installed.
Guide the package of lifters into their respective bores simultaneously. This was surprisingly easy.
Push the package of lifters until the tray fully seats.
A single 6mm x 1.0 bolt secures each lifter bucket to the block. I added a dab of Valco medium thread locker to the threads. Notice the shoulder under the bolt head. This centers the lifter bucket to the block.
This photo shows the left side lifter assemblies secured in place.
A shot of our short block, ready for heads.
A pushrod was used to fully seat each lifter. Simply push down on the lifter to bring it into contact with the lobe. The lifters are still registered in the buckets for operational orientation.
Our head gaskets are MLS type from MAHLE Victor. Each gasket is marked FRONT for easy orientation. Cooling passages must be located at the rear of the deck. The right deck is seen here.
The left deck is shown in this photo. Notice that sections of the gasket bridge across the lifter buckets. Makes sure to install the lifters before installing the head gaskets.
Our Trick Flow TFS-3060T001-C02 aluminum heads feature CNC-machined ports and chambers.
Intake ports are the cathedral style, measuring 3.250” x 1.070” and featuring a port volume of 225cc.
Exhaust ports are 1.460” x 1.670” ovals, with a volume of 80cc.
Chambers are 65cc in volume. Intake valves are 2.055”. Exhaust valves are 1.575”.
As a result of precise CNC machining, all chambers are matched at 65cc volume.
Using a pencil magnet will greatly ease installation of the inboard (recessed) main stud washers.
All head primary head stud nuts were torqued to 80 lbs./ft. with ARP moly. These were tightened in three progressive steps.
The upper 8mm head stud nuts were snugged to 22 lbs./ft. with ARP moly.
