Empi 94mm 44x37 Valve Dual Port Cylinder Head Stage 3 Wedge Port Pair 98-1437-B
These Empi 98-1437-B Stage 3 heads start off as a pair of GTV-2 castings which are machined to 94mm bore, CNC ported to the massive Stage 3 wedge port design, cut for 44mm intake valves and 37mm exhaust valves followed by a performance 3-angle valve job. These GTV-2 castings feature additional material around the combustion chambers to allow for much deeper fly cutting.
Features:
94mm Bore - fits approx. 101.5mm diameter cylinder jugs.
44x37mm valves - with performance 3-angle valve job.
Stage 3 wedge ports - flows up to 210CFM.
64cc combustion chamber volume.
80cc intake volume, 75cc exhaust volume.
12mm 3/4 inch reach plug to fit high performance spark plugs (we recommend NGK 4339 DCPR8E).
The heads are then assembled with competition dual valve springs, chromoly retainers, Manley Race Master stainless valves, hardened Manley machined valve locks, and bronze valve guides.
Sold as a pair. Includes a set of port matched Stage 3 intake gaskets - part number 00-3262-0.
We recommend the following port matched intake manifolds:
For IDF/HPMX use 45-1027-0
For IDF/HPMX with Nitrous BOSS castings use 45-1036-0
For IDA/EPC short manifolds use 45-1030-0
For IDA/EPC tall manifolds use 45-1033-0
