got an LQ4 from an 04 truck. Got a comp cams 598/605 on a 112 and a set of springs from another motor. The springs will be at the limit(918's) but my question is whether I might have ptv issues with the shaft on a 112. the 5.7 had valve reliefs cut in the pistons but the LQ4 has bigger chambers than the older 98 5.7 heads on the other motor. Any comments on how this might work in the 6.0 motor? Thanks in advance, Bill

 

any advise? Even if it's bad??
