Wanting to wake up my motor. These are the specs so far: cam 228/230/591 lift on a 112+4 , underdrive pulley, 3000 yank, pacesetter Lts, full exhaust, lQ4 stock internals. Seen alot of people use different heads on here and just wanted to get some advice on my set up. Should i go 2.5 5.3s 59cc or i could port my 317s or get 243s. thanks

 

Depends on how much u wanna through money u wanna through at it. I would suggest if u wanna keep it NA go wit some good 243's

 

Talk to head games dave he is doing a set of 5.3 heads for me now he does excellent work they look awesome and flow numbers are incredible I don't if he has pics on here but he has a website and a build gallery thread on his sierra on here

 

just wanting something to open it up more

 

lq4 or lq9?

 

243s imo that's what I'm running on my lq4
