sorry for the highjack , but can you use 4.8 heads on a lq4-lq9 block ? also what about 4.8l intake can that be used on a 6.0l .
It will choke the motor.

the intake will or the heads ? i am planing a 6.0l swap and relly want to know what i can use off my 4.8l it is in a 06 rcsb 4x4 5speed ? if need i will start my own post . thank you thomas
sorry for being a noob , now least say we use 4.8l heads on a lq4 block that gives around a 11:1 cr , can we not mill the heads or open the cc up a lil , or use a thicker or thinner head gasket to get our cr down below 11:1 , and will i be able to use my accsors of my 4.8 on the 6.0l and headers and all the wonderfull bolt on stuff , so i should be able to get a short block and use every thing off my 4.8 on the 6.0l minus heads if we cant get the cr down .
sorry for rabbling but i am trying to wrap my head around this fully as my truck just ran out of warrenty and i need more out of this truck as i will be buried in it . thank you thomas.
i am thinking you would wanna lower the cr for drivablity sake as for 11:1 cr you would need to run high octane fuel above the 91 octane easily avaliable here , would you not , also would the pcm be able to keep up with that high of a cr , i would also think to fuel it would you would need to upgrade injectors i would also want more tourqe then hp and want it low in the power band , four wheeling and towing . so if i am headed in the right direction i would assume all i would need is a short block , and possabily heads ?
