Default Re: Day 2 Valve Covers

I have a few sets of these, even the staggered hole versions (but sadly no 9 fin pieces). The last pair I bought direct from GM was probably in the mid 70s and only one of them had the casting line through the O. The few sets I've picked up in recent years all had the line.
I've heard the story about the crack in the mold, and also that the molds were sold to a foundry in Mexico. [img]<<GRAEMLIN_URL>>/dunno.gif[/img]
