well i got a lq9 and i did a compression test all cylinders are between 122 to 129.i didnt lap the valves cuz they were new although heads were disassembled.and the motor is still new has around 1,000k

 

Aftermarket cam ?....more info

 

pushrod lenght?

 

torqr v2 cam 7.4 tsp prods and prc 2.5 5.3 heads lq9 flat tops idn wats the problm when i put valves in i looked in the ports while haveing a flash light under the head where the valves were and didnt see no light so i figured it will be ok

 

Does it run well or is it lazy ?? did you verify correct lifter preload ??

 

it runs good i been driving it for couple months.i gone out to back roads and ragged on it sounds smooth doesnt miss or anythin but i no it should run stronger and faster.pre load im not sure i used existing lifters that i had in the motor but i even loosen the to rockers to ensure there up and put air in cylinders and dont hear no air leaking.i really dont no wat the term pre load means and how to check the clearance.but everyone is telling me the pushrods are correct size
