Trick Flow small block heads

When somebody says "somebody needs to prove to me they are worth their money on the ET slip" throws out the Quality factor. If they are only worth 2 tenths more than the Eddy, it doesn't mean it was a waste of performance money, if one considers the Quality. So many threads on this site about poor quality, poor fitting parts. Any part. Yet, when TF puts together a quality head, so many say "before I pay the extra 500 bucks, I want to see a big difference on the ET slip". Complain if they do, Complain if they don't... LOL
WOW!!!... Again 100% agree.. but oddly enough you're the first one to come out and bash the hell out of me for putting 4k into quality Parts and machine work for my motor LOL.. I got to admit that came across pretty hypocritical...
