I started my port and polish job on one of my heads tonight. I found numbers 1-4 stamped in the intake and exhaust ports. Does anyone know what the numbers mean? I check my two other heads and there in them to. I've got a 1.5, 1.6, and a 1.6TD. I got my first Bentley today. It didn't say anything about these numbers. I don't know why I bothered with other manuals. The best money I ever spent.
