low deck and tall deck Desoto ports

Post by johnny5 » Fri Jan 15, 2010 9:05 am

Does anyone have the port sizes for the tall deck Desoto heads? I can measure the 291 ones I have myself but I don't have a set of 330/341 heads.

I'm almost certain the later tall deck heads have larger ports, but I have not ever measured them

I've heard that too but no one has ever confirmed it. If they're the same size though then the low deck heads are better rebuild cores. The RB ones tend to crack in the chamber. This must be a casting flaw. Never happens with the little guys.
