Time to do WURK!
Can't say enough about these heads! If you didn't know! Then you need to know! These are the new LS7 heads for 4.060 bore (min.) engines! They are not small bore they still utilize ls7 stock valve sizing and flow close to 400 cfm! They are also 6 bolt and feature ¾Â deck. These came built to the hilt from TSP they feature:
265cc Intake Ports
2.20-Inch Titanium Intake Valve
1.61-Inch Stainless Steel Exhaust Valve
PRC .700' Dual Valve Spring Kit
The Springs were setup and verified by TSP to be installed at 1.8" installed height.
1.080"-coil bind + lift .657 + .060 from coil bind is 1.797".
The .700 lift springs are rated at [email protected] they shim them .050

Packaged perfectly! Love at first sight!



Mmmmmm CNC chambers! Please not this is how a properly ported head is supposed to look! NO CHISEL PORTING HERE!





Intake side



Exhaust side





The whole shebang!



6 bolt provision and you can see the difference in spring height from ex. To int.
Per TSP recommendations and the way the heads are setup you are only able to run GM LS7 rocker arms which is perfectly fine just make sure you do a trunion upgrade





Deck Measurement! The beefier the better!



Went with GM LS9 7 layer MLS Gasket! These have done great on several high HP builds and look to be a lot better than normal cometics. These will be installed dry (no copper coating.) these gaskets are 0.051-inch thickness which will put my Cr around 11.1 perfect for boost and e85!



Looks good!



He who is rarely caught on camera came out and gave me a hand with this as it would've been a bit more challenging without him.
Sir Bentley himself! Ladies and gentlemen no but on a real note thanks a lot man I really really appreciate the company and was fun as hell for sure! (the nicest guy you'll ever meet, Dammit he makes me soooo angry LOL)



Studs in

Heads on



Torqueing those suckers down!



Sneak preview!



The night was cut short when we somehow ended up missing 1 washer so going to try to find one locally or source one out next day air!
