Part No: HSP-4 (4-Cylinder, V-6, V-8), HSP-6 (Inline-6)

For years cylinder head rebuilders have known the value of straightening overhead cam, aluminum cylinder heads prior to surfacing. With the sparse availability of several common heads in today's core market, straightening capabilities are a must and the only salvation for these heads.

With the HSP, the straightening process involves bolting the head to a solid base plate and forcing a reverse bow. The assembly is then oven heated to relax the cylinder head so that after cooling, the head is straight enough that the cam bearing bores do not require align boring and the deck surface is flat enough to only require a minimum amount of material removal.

BHJ Cylinder Head Straightening Plates are manufactured from the highest quality stress relieved cast iron which retains its flatness after repeated use. These castings are surface ground both top and bottom to precision, commercial tolerances. Central clamping studs are mounted in eccentrics which allow adjustment to the head bolt center distance to accommodate any head. This eliminates the need for having multiple holes drilled and tapped in the plate with the possibility of the threads stripping from constant use.

Stainless steel studs, nuts and washers are supplied for their superior heat resistance.
