I appreciate it but my interest in big block stuff just isn’t there right now so I’m limited in testing stock. My 440-1 heads flow in the 375-380 area so info from that head wouldn’t help many. That head needs an Indy intake. I have one stealth head and one Edelbrock head that I started years ago. Without a mate it’s wasted time for me to finish them. With shipping costs now and the run around I got from the last member this is local only. Thanks.
