Preferred Head Gasket

Installing a TFS A-460 18 bolt head onto a factory 10 bolt block. What is the preferred head gasket to use, a 10 or 18 bolt?

Thank you,

Tony.

I don't know if this will help you or not.

For what it's worth they show a FelPro 1028 below 4.660" bore diameter at the bottom of the link.

Be sure to use a gasket with at least 4.600" bore on the TFS A460 heads regardless of the block bore.

Lem will get you fixed up with the proper parts.

Well, after a very short wait, Lem Evans has gotten me all fixed up with several items that I needed. He was a joy to visit with, and I am looking forward to placing another order with him when the time comes. Appreciate everyone’s responses, and wish you all a safe and fun racing season that cannot get here soon enough!
