We make our heads from primary A-356 with a t-61 (extended age) heat treat.

That would be great if the ETP cylinder head line is more consistently available going forward. The AFR heads, and then the TFS heads became very popular mainly due to (1) availability, (2) decent quality and portwork, and (3) eventually price - TFS heads have been priced well.

So for the four bolt crowd... Who makes the thickest deck? ETP or AFR?

I think AllPros were right up around there too Reiko. TFS heads might be too. Seems to me that .800 was pretty common except maybe for the Dart offerings.

My cousins friend is doing a LSx turbo in his truck... He wants to put a aftermarket head on it for when he throws boost at it so the head doesn't wonder around... He asked me the best head with the thickest deck a few weeks ago and I told him I would check around...

Just don't want to steer him wrong...

The strongest decks will have the best alloy, best heat treat and then the most material. So far, ETP (now LX Racing Products) was the only cylinder head with these three criteria.

How do their heads differ from say AFR heads?

It would be easier to name the similarities.

1) They both will bolt onto an LS engine.

2) sorry, no "2"

Valve angles are changed from the factory 15 degree to 11 degrees, 12 degree on LS7 style heads. Valve location is different as well. The spark plug has been relocated, the valve length has been increased to allow for larger ports and larger valve springs, the rocker mounting system is unique and reinforced, the valve cover rails are raised to allow use of the stock valve covers in most applications, as well we offer race cylinder heads, not just street performance which seperates us from the other companies except for AllPro which has similar offerings in the LS7 market. That is most of the differences. As well we offer the 6 bolt configuration on all models of our cylinder heads. Yes, our heads are a little more expensive, but they are a superior casting and alloy and that will carry a superior price. We also use superior hardware too (valve seats, valve guides and severe duty valves, not the most inexpensive alternative) They are not for everyones budget, but you will get what you pay for. We have quite a variety and offerings.

A little modest aren't we?

You forgot the mention the kick ass CNC program and high velocity port designs just name a few other differences.

Oh, I forgot, we have intake manifolds to fit all of our race heads too. So the days of having to buy sheetmetal/custom manifolds just to find a fit are over, well unless you have an engine sitting under that dashboard.

Ron, I can sell you one of Cary's intakes. In fact, I'll sell you the whole damn car!

Cary,

You neglected to mention these heads can be custom tailored to fit any application. Like those 245's for Christian's new HKE engine... which were *shweet* by the way...

Now get back to work on the small bore LS3 heads!
