Here's my reply from a post on another board about them.

Now Doug Thorley was the father of Tri-Y Step Headers which which povide better scavaging and increased power though out the whole rpm range. The original design was I think don't quote me was that Exhaust port 1&3 and 2&4 converged into a Y and then those two y's meet into one collector. LFP's headers do not have the initial Y's but 2 Y's are formed before the collector (not sure which Cylinders merge together). This is suppose to increase low end HP & TQ and make constant gains thru the rpm range. This is the big difference between LFP's and the rest so far.

Has he fixed the angle of the egr tube yet? You will waste 1-2 hours re-bending yours to work, and if you haven't tried it that tube does not bend easily! I finally kinked it and had to buy a new one and bend it all up.
Has he switched the bolts for the heads yet? They came with allen bolts which are almost impossible to tighten in some spots. A 6 point headed bolt is MUCH easier. Expect to at least modify an allen wrench to work.
His lower flanges always leaked at the collector on mine, although I replaced his gaskets with a harder steel donut which helped.
Dynatechs had none of the above issues. Kook's are awesome quality also, have a set of their turbo headers for a Camaro project I'm doing.
