Generation IV Internal Engine - Best LS7 6-bolt heads

I'm getting ready to buy some LS7 6 bolt heads. I would like to get some options on what one to buy. RHS LS7 6-bolt 291cc runner with 2.20 intake valve, PCR 285 with 2.25 intake valves Texas Speed and Performance version,Warhawk 285 2.20 intake valve, or Have my 265 LS7 converted to a 6-bolt. Thanks

Are the RHS heads out yet?

MAST has a couple versions you might want to consider as well.

Proformance Induction heads. or HCCW.

I have spoke to Sean and they are close to being out. He is going to email me when they become available.Sean also was going to check to see if he could start taking orders for them.

All Pros by WCCH.

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. :) :)

All Pro and MAST canted valve are Kings of the Hill

I have been looking at the Mast heads and like what I see!! Has anyone used mast motor sports ls7 cnc splayed heads? or the Rectangular Port LS7 305cc 12 Degree 6-Bolt Large Bore ?

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?

Mast/P.I.S. heads or All Pro from WCCH would both be fine choices.

have tried or heard any thing about the Mast LS7 splayed heads? Leaning toward them.

Excellent choice but I don't believe they're available yet.

We don't do trade ins, but shoot me a pm when your ready & maybe I can still help out some!

Here's a video for you guys of the PRC LS7 aftermarket casting heads on the cnc getting ready to go to customers!!
