Had my heads flowed by Barnett Performance, the intake flowed 375CFM and the exaust was 220CFM both at .700 inch lift.
The intake lost 5 cfm between .700 and .800 lift but the exaust continued to improve

I would like to stay around .700 lift can the exaust be improved to flow more at .700

I don't have much to add here, but I want to say that those seem like pretty good numbers for those heads. I imagine that they have been extensively ported? Any pics?

I would imagine that the exhaust could be improved. I have those type of exhaust numbers in my home ported 915's

IIRC they should have a 75% ratio intake to exhaust.

Great numbers on the intake

Who ported the heads, they should flow equal to fully ported -1 heads since Loren's heads were the predecessors to them. John

Those sound great..
What needs to be asked is, if the flow bench operator used a tube or not on the exh side..
That can easily move them up a good 25% in flow or close to it..
