Stock head bolts can't be used to install Dart's Iron Eagle cylinder heads on a standard 8.2-deck block because they require a 1/2-inch bolt.
ARP's stepped head-bolt kit is called into action and Greg torques each fastener with 75 lb-ft of torque.
After installing the 7/16-inch studs included with the Iron Eagles, Greg topped off the new heads with 16 of Harland Sharp's Diamond Series roller rockers. Per the AFM cam card, we're staying with a 1.6 ratio for the rockers, and as usual with a hydraulic-roller cam, lash is adjusted to zero. The 1.437-inch double springs and steel retainers on the heads are included, but the stock pushrods are reused with this setup.
Before positioning the BBK SSI Series intake on the engine, its lower intake must be pre-assembled with the high-flow fuel rails, regulator, crossover tube, and all of the various EEC sensors. This lower manifold features long equal-length runners that deposit air/fuel into a huge, open plenum area. Based on the intake's overall design, we think it should work well with the heads and our selected camshaft.
BBK includes two O-rings for the fuel crossover tube. However, due to the tube's location below the upper manifold and the difficulty Greg will have trying to access the tube once the upper is installed, he adds two additional O-rings (one on each side) for added insurance against a possible leak.
The engine's original vacuum T must be transferred to the boss in the SSI upper intake.
Before lowering the upper manifold, the main engine harness and other wiring must be zip-tied and moved completely out of the way. The SSI upper is a lot bulkier than a stock 5.0's, so the more clearance you have when installing it, the better.
