I have a 440 stroker with a big cam, single plane manifold, Dougs headers etc and the heads are Eddy Perf right out of the box. The car runs fine but there is surely more to get and i am looking into a head upgrade. My current setup is probably like on a hot day, sucking cold beer with a straw...
I have 2 options on heads, either get new TF heads and bolt them on (safe but higher cost) or have my Eddys ported locally (much cheaper, i am not in the US).
My own practical experience with head porting is nada, what i know is theoretical. My dilemma with having them ported locally is that no one has done a US V8. There are shops with a very good record, educated machinists and a lot of happy customers. They have flow benches, CNC machines etc but they do mostly 4 and 6 cyl Japs (built for RPM).
To quote one shop owner i talked to: instead of 1 head for a 4 cyl, i come with 2 heads for a V8. Same principle, give us a target flow curve and we can do it.
There is some sense in what he is saying but that easy...? Not sure... Or is it the same thing?
I know its hard to advice and in the end its just my decision. CNC porting here is much cheaper than at your end but if the car runs worse after porting, add cost of new heads. What do you say?
Did some search here on TF heads and it appears that some members have them. But, i cannot find any post on real driving experience with these. Flow numbers we can find online but it would be interesting to have a comment after some test driving. Anyone?
