Which Retainers and Locks

Okay, I got my Comp Cams Pushrods in today. So I now have CC 1.7 Roller rockers, CC Pushrods. I was going to purchase some LS6 springs (I dont believe I would have an issue with valve float even on stock springs, but I want to be certain, so the LS6 springs are just a tad bit higher seat pressure and should deal with that margin) but I dont know if I need LS6 retainers and locks? Can anyone comment on this? I thought I remember seeing somewhere that if you used LSx springs, you had to use their retainers and locks, but I want confirmation. So if anyone has some info, please post up.

So here is what I have so far.

1. CC 1.7 Ratio Roller Rockers (Done!)
2. CC Hi-Tech Pushrods, stock length (Done!)
3. Rocker collars & Rocker Bolts (shaft mount) (In Transit!)
4. Viton valve seals (Pending)
5. LS6 springs (Pending)
6. Steel Valve Spring Retainers (Pending)
7. CC Valve Locks (Pending)

What else do I need? Should I got ahead and replace the lifters as well? Also, will all this I have now work with L32 heads should I be able to get my hands on a set of those?

Feel free to post up and ask for any clarifying information you may need. I want to do this right and with the best parts I can afford. Just so you know, I know the OEM ratio is 1.66. I am after a little bit different things with the 1.7's than just raw power and if I should ever want to upgrade to 1.8's, I want to be ready on everything else, but I dont foresee it happening right now. I just wanted roller rockers in a lower ratio.

One last thing, if I should need to get new lifters, do I need new lifter trays? If so, what's involved in replacing those? Do I need to pull the heads to do that?

Thanks in advance.
 


When I got my 1.9rr's I got LS6 springs and the titanium retainer/locks don't reuse the stock locks, better safe than sorry.

Where did you get the titanium retainers and locks from? I cant imagine titanium hardware being cheap.

The locks were just regular, the retainers were from ZZP.

It seems they don't have the option for the titanium ones anymore, just steel and modified steel.

"CompCams 7˚ titanium retainers are American made from 6AL4V alloy and then heat treated. For performance without compromise these retainers deliver! Titanium retainers weigh 7.5 grams."


EDIT: Intense has some titanium ones also.. $149.00
 
Okay, cool. I dont know my situation will warrant the need and expense of titanium, so I'll probably stick with the regular retainers then and regular locks. I guess I can add that to the list.
 
Okay, so I updated the list above. I guess the next thing is whether or not I need lifters, if so do I get the lifter trays and what would be involved in replacing the lifter trays if needed. As well, will all the items above work with the L32 heads.

This I have no idea on. I didn't replace my lifters. Someone with more expertise will have to answer that. :)
 
I think that Ron's engine is a testament to the ruggedness of the stock lifters. If they use them on the 400hp LS1 engines....(and they do) then they're good enough for the 3800.

But that's just my opinion.

interestingly enough, i had collapsed lifter issue w/ my stock cam / 1.9 roller's (stock S/C pulley at the time)

but everything is bound to have a few bad ones.
 


i wouldnt worry myself about the lifters run your stock ones, aftermarket ones are the same thing anyways with someone elses name on the box.. there are also aftermarket lifters that when they pump up they turn into a solid lifter, those are junk stay away from those.. its basically a waste to get aftermarket lifters when the stock ones are the same and way cheaper...
 
Are most of you guys replacing your locks? I've only heard of people using origial stock locks. Is this bad or what? If so, I better buy some locks...
