question on blowing head gaskets

[Big E tech]

can anyone tell me the difference between the 8993PT-1 and 1035 felpro head gaskets? also where can i get my hands on locator sleeves? A motor i bought didnt have any

The 8993PT-1 head gasket is a standard folded fire ring style gasket with a 3.920" bore and it's .051" thick when compressed.

The 1035 head gasket has a stainless wire inside the fire ring. It also has a 3.920" bore and is .051" thick when compressed. The stainless wire inside the fire ring creates a higher clamp load in that area because it doesn't compress as far as a standard fire-ring, but that also imparts more stress into the head and block causing them to deform over time... Also, the 1035 have been discontinued but are still available in some warehouses due to their slow sales.

If you are looking for head locator dowels, call Esslinger Engineering, they manufacture short ones.

Just remove the same amount off of the alignment dowls.
The 8993 head gasket is .045 compressed where as the 1045 is .041 compressed. (per Fel Pro specs) There is also a gasket made by Corteco which is .051 compressed however it is also a slightly smaller ID. Also do not over torque these heads, if you do you may distort the top of the block and be sure to use a torque plate.
