I ask cause this hardwares going into a jeep 4.0 inline 6
I bought the 6.0 LQ4 stock hardware for 42 bucks. And then just saw the yellow Z06 springs for 12 + 12 for shipping lol. But from what I've read the Vette forums, the Z06 springs are drop in and go..at least what I read was that 1 guy broke a Z06 valve with a big cam (common issue for 02-03 I guess), and used a LQ4 valve as a temp replacement until he could get aftermarket valves.. Had pictures and all, so seems it'll work out!
I want Z06 valves, cause after some quick searching, I found out that LQ4 valves get valve float with a stock cam around 6krpm. A few times I read that. I'll be running a custom grind/remade Comp 239 .493/.512 lift cam at 106LSA. The regrind was for a 106Lsa and a built in 3* of retard because the cam is made for like 5800rpm, retarded it to get it down to around 5400rpmm, And lower Lsa cause I wanted some lope. Its like the 3rd biggest cam offered for us jeep guys so I wanted to be safe!
Heres the comp 239 idling away..mine should lope slightly more than this with the lower Lsa and slight retard..hoping to keep my 650rpm idle

Not bad getting a full valve train that weighs less & is bigger/better than stock equipment for under 75 bucks huh?
Replacement jeep 1.91/1.50 valves are 11 bucks a piece, not stainless or anything, just replacements! SBC SS undercut/swirl polished valves can also be used & require less work to make them fit than LS1 stuff, but around 80 per side..or 160 for just valves & they will be heavier than stock jeep equipment, still need springs & such which is even more $$$.
So I hit ebay and found Lq4 valve train & now Z06 springs..they will weigh less than the Jeep or SBC stuff, are slightly bigger 2.00/1.55 and tuliped undersides so I can get my quench height tighter without bumping my compression ratio!
LSx stuff is deffinetly the best choice lol.
