My neighbor Earl runs F/SA with a 68 340 FB Barracuda...Having lunch with him tomorrow..
I bought a set of X head castings from him last year for this project.
The 894 heads are not the best head to run. The quickest F/SA 340 in the country runs a different head that flows much better as does a certain six pack car(when he runs steel heads). I have known Earl for years he has spent a lot of money and blown up a lot of parts.
