Heads for 440

PRH said

As I previously mentioned…….the plugs are not an issue with the FW headers.

I have customers running them with stock rockers.

I guarantee you there are tons of cars running Ede heads, and all the copies, with headers smaller than 2”.

Oh ok..I knew you said the fenderwell headers make the angled plugs a non-issue but wasnt sure about the 2" header tube thing they mentioned, and why they would say you HAVE to use adjustable rockers. So they have 2 different versions of the 84cc RPM heads, which one do you recommend for my setup?
Edelbrock 60929 Edelbrock Performer RPM Cylinder Heads | Summit Racing
or
Edelbrock 60925 Edelbrock Performer RPM Cylinder Heads | Summit Racing

The 60925 does not state the rocker arm or header notes at the bottom like the 60929. The 60929 is cheaper.
