They have a good reputation on here, never used them myself though.

Sent you a PM about my setup.

I have heard good things about SDPC, but I don't have any personal experience with them to offer.

Can't go wrong with WCCH for the LS3/L92 port programs. I have never purchased anything from them directly from WCCH but Richard spent time with me on the phone going over his work to the heads I bought used and applications for them along with spring packages.

My LS3 heads should be shipping back to me from AI really soon. A friend of mine has SDPC ported LS3 heads on his stock displacement LS3 swapped into his 4th gen...I didn't see his heads off the car though, and his LG G6X3 I think is more aggressive than the cam I'm going with in my car...and I have a Tony Mamo FAST 102 versus his stock LS3 intake...so I guess it won't be a really fair comparison though. I will post up results as soon as I can, I'm looking forward to it.

I did tune his car...so I will do my best to compare what I can when it's all done.

Richard (WCCH) did my L92 heads also. I should have the car together soon.

Great person to deal with!!

WCCH was another option for me as well, can't say anything bad about WCCH or AI in my opinion.

Got my heads back today...the machine work is very very nice...I'm very happy so far.

Wish me some good weather in New England so I can get the car out of the garage and running/tuned sooner than later!!! The sooner I can make that happen (without getting salt on my car) the sooner I'll be able to post my results.

The heads do come back from Ai looking great. Almost makes you not want to install them on the car, but the results are even better than the aesthetic appeal!

I'm using the SDPC lsa/ls3 cnc'd heads with the manley race flow valves on my 408,car is making good hp with them.The only thing I would do if you buy them is get rid of their springs and put on a set of pacs.
