Are they overkill?
Maybe.
Are they too much for what my build is?
Probably not.
These heads flow the same as the stock rectangle ports on the gen4 motors. That will work for me. I may want to upgrade my throttle body at some point. Or not, we shall see how it runs.
I’ll probably need bigger injectors, but the was a possibility as soon as I went with more cam.
These heads came with some mongo .700 lift springs (second pic) that were actually overkill. I swapped them out for my Summit springs. That gave me a chance to check out the guide clearances. Night and day. Mission accomplished.
