PRC stage 2.5 5.3 heads discontinued? Just when I make up my mind to buy the above heads, I go to the Texas speed site and it looks like they don't carry them anymore.
Am I blind and just not seeing them?

i'm running those heads... i think they're great.
i hope they stopped selling them because they weren't making much money on them and are focusing their efforts on the LS6 heads. somebody mail me some xanax...

We have taken them off the website for now because of casting availability problems. As you know, they haven't been installed on an engine by GM on the production line for several years (close to 5 years), so casting availability is becoming an issue. As always, we're working with suppliers to try and keep a flow of these cores coming in, but it's tight enough right now that we have had to take them off the site.

We have always used brand new GM castings. We are just low on our inventory on these. We will port a customer's used 5.3L castings if they send them in, but I do not forsee us buying a bunch of used heads to port and send out.

LOL! Get them for sale as limited with some great mark-up, and get into the aftermarket casting heads for no extra money out of your pocket!

the 243's are a better cylinder head,with a better chamber design.The 5.3's offer a smaller chamber for more compression without milling.The best thing to do is use 243 heads and have them ported,milled,and use a cometic .045 gasket.This way you get superior ports,better combustion chambers and high compression with excellent quench.All this adds up to produce more power,better gas mileage,and a car thats easier to tune.
