Glad your son us ok. Anything promising yet?
This was my thinking as well when I gutted my heads. Im hoping to flow them on Saturday. If I reuse mine, I will most likely upgrade to 2" headers since I'm being told I have left power and scavenging on the table by port matching my exhaust ports to my headers. If I use the Folxlake heads, I will port match the intake ports to the JPC intake and ported delete plates and leave the exhaust ports alone.
Heads have been flowed on the heartbreaker back to back on the same bench. The Foxlake heads have stock size valves and mine have 1mm lager ones. Im sure the larger valves are the reason for the higher flow numbers up top, but Im pretty excited either way. Looks like my heads stay on my motor and the FL heads go on the kids new motor.
Here are the results. Keep in mind these are on a heartbreaker flow bench. But the key thing is, both were done on the same bench in the same conditions.

First and foremost, I'm very glad your son is okay from the wreck, that totally sucks but of course the car can be replaced..
Now re the heads, Congrats! That's great! Your heads outperform the Foxlake throughout the entire lift range in the intake side, and it's interesting that yours are better on the exhaust mid-range but lower and higher range the FL outflow. In any case congrats on great work to your heads.
Aren't you already running 1-7/8" ARH headers?
Main caps are stock?
