I never had Dan Flow my HOs. He first ported them for a street-strip sft cam. And then sent them back to be set up for solid roller and some further port work.
I ran them so long a little oil pooled on top of the valves when it sat.
Right now thinking about having Paul Carter do some work to them with custom smaller stem valves based on the late Dodge Hemi valves. Sort of like he did with his 670s that flow over 280cfm.
He thinks we can get 300cfm out of them with those and a little more work. Never seen or heard of a 300cfm pair of HOs, not sure if it can be done but maybe get close.
After I run the High Ports on my trick for me shorblock I will see what can be done with the HOs again.
Don't plan on running it super hard with the High Ports. Dans last block so I want it to live.
See if I can get that 9.3 CR 10.80 deal quicker yet.
The old school stuff is fun.
Paul K, have you ever messed around with the smaller stem valves like PC has ?
