Call Texas Speed and ask if they mark them anywhere.

For the past year or year and a half we've been grind down that particular "243" casting and cutting "PRC" into that spot. So if they are PRC's, they are a good bit older. Up until about a month or two ago, we didn't put unique serial numbers on them. Now when you purchase, your invoice, the cylinder head, and our work order for the heads all have a unique serial number on them so we can track them better!

Anymore pictures? Of the runners,chambers? still would be hard to tell bur maybe they would recognize thier machine work? Like Matt said over a year ago thier heads leave with PRC compenents and STG 2.5 there where the 243 is.

I have the older ones (2+ years old) and they have no markings on them what so ever.
