I have been looking at the LXR-ps7 heads and would like to know if they have .400" Raised rail allows for use with aftermarket rockers; .100" raised exhaust port allows use of both stock & aftermarket manifolds like the RHS head does?

Simple choice MAST Black Label Large bore heads. They are truly a work of art. Should be in the mueseum of modern art honestly. They are one of those things if your a car guy, you cant help but get giddy lookin at them.

Not to sound dumb but are the mast heads and the LXR heads the same?
We have the PRC LS7 cylinder head castings coming in finally after tweaking a few times! We will be pricing them very very reasonably so you dont have to pay $4000+ for a set of LS7 heads! Give us a call & we can get you some information.

In 2007 I bought my LS7 from you guys. The invoice number 22857. The signals got crossed and it was a 11.4 motor too high it was going to be a low compression motor. Because I run 16 psi boost.I have been fighting this for 4 years now. So now I'm going to pull motor and send it to ERL and do a 6 bolt conversion and I was going to have my heads done by LME to convert them to a 6-bolt head but found out I have the 265 heads that do not flow very well. Do you take trade-ins?LOL Do The PRC heads have a raise valve cover rail? How do they compare to the Mast heads? ls7 305cc and the new ls7 cnc splayed heads?
