WCCH or Texas speed
so I'm looking to get my factory LS7 heads done and found out the texas speed also will redo your supplied heads the same as WCCH. does anyone have experience with which shop is a better choice? Texas speed was alot cheaper and WCCH insisted on getting my rockers done while Texas speed said only do trunion upgrade. I do run a E force supercharger and full exaust. I will be buying a cam, springs, rods..ect to go with the heads. Any input would be great.

I was leaning that way but his price is about a grand more than texas speed with all the parts as well. but WCCH says to do rockers which is about 400 more, while texas speed say only trunion upgrade. the head job at WCCH is 1600 and only 1080 at texas . so idk. lol.... I want to only do this once while I have my Z so I want it done right the first time!!! also should I replace the timing chain set?

There are a number of places to choose from on cylinder heads if you are wanting some upgraded parts done and more importantly the valve guide fix.
We offer this service as do a number of the top shops you can find here on the forum. If you have any questions about our cylinder head service, either install or mail order I am more than happy to help in any way I can.
If you have narrowed it down to those two for a repair, I would go with WCCH.

But the LS7 head...the original GM head....is a very good baseline design if you forget the guide issues. If we are talking big HP, or big boosted engines then going to a bigger port and 6 bolt head design would be the way to go, but most of the aftermarket ones ( the good ones) are of a much bigger port design which does not lend itself well for a normal cam'd street/strip car.

Just came across this and thought I would chine in, WWCH is so darn expensive because they operate out of Van Nuys (HollyWood/LA area) compared to Georgetown Texas. It's much more costly to run a business in California then Texas.
Cost of a gallon of gas
California: $3.89
Georgetown Texas : $2.00
Texas Speed does top notch work. Don't discount them because they are cheaper. They don't have the operating cost that businesses in California do. I run a pair of their LS6 heads and their customer service is top notch and I have a 520hp LS1

WCCH is a more "hands on" operation where Texas Speed is more like an assembly line.
Richard is probably telling you to do CHE rockers which seem to be way better than the trunnion upgrade. There have been quite a few reported problems with those.
I feel your pain though. The US dollar kills us on this stuff.

The LS7 core PRC portwork definitely outflows the WCCH program. Roughly 18-20cfm from .400 onward on the intake side and 8-10cfm on the exhaust side.
With that said, the AI portwork and guide replacement is in the same realm of cost as the PRC but the AI program outflows the PRC program. If you have cores to send in, you should shoot Fran a PM and do an exchange + cash deal for the AI heads. He typically keeps them in stock. I've seen two local guys pickup 2-3 MPH in the 1/8th by going WCCH to AI on LS7 cores. I just swapped to a set myself and look forward to seeing what they can do in the next few weeks.

How do you figure TSP doesn't give the same love as wcch?
Who is Fran? Can you shoot me an email?

I have personally spoken to Jason at TSP, and I don't feel they run any differently then anyone else. I have also spoken with Phil at AI and their prices are among the highest. His basic package also doesn't include porting as compared to TSP which does for the starting $900 price tag.

I agree, based on what I have seen and talking to these folks, AI, WCCH,TSP, and AHP all do excellent work and produce products that perform quite well. Geographic location and parts used will drive the differences in price.

If it was for an all motor build the only two head choices I would consider these days (without getting into crazy stuff) is AI or Mamo TFS stuff.
Short of getting into the $10k+ heads/intakes those are the two best performing setups IMO.
