I read a lot on here about Phils heads and they flow 278plus. Are they talking the econo port or the full port. When they compare them against Lloyds, which set are they comparing? Are the AI econo port heads as good as Lloyds? I know this subject is controversial but $1795 plus is a lot to spend and I want to be sure. Thanks

 

The 278 CFM would be a full port job.Econo would be around 260 CFM.I am sure Lloyd could do either,ask him.

 

From what I understand the econoport too bad... people making some good numbers with that
I ain't never had or seen Lloyd's heads in hand but I have Advanced inductions and their stuff was top notch. If I had todo heads/cam all over again I would go to phil w/ the same full port job. He will be doing the AFR's on my new motor also.

 

I made 405rwhp with AI's econoport but now I wish I'd gone with the full port job.
