Weiand heads

[ken-r-mer]

Anybody know where to look for the stamped compression numbers on the Weiand 8BA flatheads?

The Weiand head I have is stamped 2 places,on the gasket surface and near the water outlet.
stamped on the gasket surfaces lets you know if it was cut changing the compression ratio.
It’s not a 8ba head though.

The 8BA ones I'm looking at have no visible stamp near nor around the water outlets. No visible marking on the gasket side either. For a 70 yr old set of heads, the chamber side surface looks better than average, so maybe it's been resurfaced eliminating the stamping. Looking for a low compression set of heads for a blower setup or....will have to resort to a thicker head gasket to lower the compression closer to 7.0. Per Roadrunner's charts Weiand had the highest cfm air flow numbers unless you get into exotics like Baron's ($2,600.00+, 6.1 C.R.). The price may be due to the 2nd name on the head (Tattersfield). $1,300 per name.

The large chamber edelbrocks flow pretty good from what I remember and they ate like 7.4 c
