Heads for 440

Speedmaster 74cc heads are copies of Ede Victor heads and require some special parts to be able to use them.
Offset rockers being the main thing.

If the OP wants an aluminum user friendly version of a stock head with straight plugs……there are really only two choices.
Stealths, and the 84cc E street head, number 5093(which are way more $$ than the stealths).

With FW headers the angle plugs are a non-issue, and the Ede 84cc RPM head(angle plugs) is a better deal than the E street 5093……but is still a few hundred $$ more than the Stealths.
