Question Ls7 cylinder head LSX part interchangeability

Hi,

a couple of intake valve seats have cracked on my LS7 race engine and I’m looking to replace the head with the LSX-LS7 head, i know this has a thicker deck 0.625” v’s 0.400 but can anyone tell any other differences and whether the stock LS7 valves, springs and rockers will be a straight fit please ?

the current LSX-LS7 part no is 19419193 that replaced part nos 19354241 and 19329962, can anyone tell of the differences between each of these, the generic description is the same for 241 and 962? Both are described as

Tech SpecsFully CNC ported
  • 6 bolt per cylinder bolt pattern
  • LS7 style rectangle port design
  • Assembled with 2.200" titaniun intake and 1.610" sodium filled exhaust valves
  • 12 degree valve angle
  • minimum 4.100" bore
  • 70cc "as cast" combustion chambers
  • Handles .650" lift
  • Uses LS7 rocker arms and LS7 bolts
  • Flows:
  • 397 cfm @.700" intake
  • 230 cfm @ .700" exhaust

Thanks 01Camaro and Corona,
do the standard intake and exhausts all fit the same or do they move up or down, sideways ?

cheers
David

Did you know Darin's already left Mast? Wonder what went down there. Would have been really nice to see what he had to offer their Black Label line

Everybody and there Mom knows he Left?

I posted a Video of Darin wearing a BES shirt in a cylinder head thread....
Ummmm 🤔 it's 3 or 4 videos in the Thread...

He can still do any head as a Hired gun now working with BES......may even have a few programs...

Cost? $5k+


I'd just get a pair of FED 710's and Dave would get CID heads

You should see my Phone Interweb Book Marks ....
I'm now breaking it down into sections....

Newest one is Factory block LS cars that run 9s or Better .....Spanks 👍 I had more than enough to start it but Spanks pushed it over the edge.

Maybe Mavn also like I said ...it Should if the suspension is set up correctly...
