Head studs, oil pan gasket and rear main seal for the Ford SOHC

The small sealing parts that keep a rebuilt engine from leaking or lifting a head gasket.
A rebuild is only as good as the sealing parts that go with it. These are the three we sell most for the Ford SOHC.
ARP head studs
The ARP head stud kit fits 1974 to 1997 Ford 2300 SOHC "Lima" engines and 1998 to 2001 Ford 2.5L SOHC "Lima" engines. Compared with the stock bolts it gives more consistent torque values, higher clamp load on the head gasket, improved cylinder head sealing and a lower chance of head gasket failure.
One piece rubber oil pan gasket
The 1pc. rubber oil pan gasket fits all OBD1 Ford SOHC blocks. Early blocks that have M8x1.25 bolt holes next to the rear main cap and in the front crank seal holder will need our oil pan corner studs, or the inserts in the gasket removed, or the block and seal holder converted to M6x1.0 threads.
Rear main seal
The 1pc. nitrile rear main seal is the same one we use on all of our SOHC engines, from 100hp street 2300s to 380hp methanol burning 10,400rpm midget engines, and on up to 1200whp turbocharged engines.
