Trick Flow 440 heads, The Real Deal?
Many things I haven't been able to check yet, but I can tell you this.
Even with Trick Flow there is still no such thing as a bolt on OOTB cylinder head. I haven't checked seats and valve runout, guide clearance, install height, etc but with all the aluminum shavings in the intake and exhaust ports you still have to dis-assemble and clean these things before you run them.
