You'd have to ask Weingartner, you're referring about the flow sheet right?

These aren't my heads, I boxed them up & sent them to Weingartner and handled all the communications for the owner, is all.

All the sbc flow sheets I’ve seen from heads that were ported show the flow to 1.00. I believe this is standard. The intended cam was .660, but someone else could do a 1.6 rocker and get more out of this head with same cam or different cam.
