Having an interesting time with Comp 1732 tool retainers. I made the decision to run Comp tool steel retainers instead of Titanium on my 500 street/strip motor. When I installed them, I found that my installed height went from 1.878 with Edelbrock steel retainers to about 1.954 with the Comp 1732's. So I tried my MP Titanium retainers on the same valve, same locks, the installed height was 1.88. Then I tried stock mopar retainers, same 1.88. Out of curiosity I measured every one of the comp 1732 retainers on the same valve using the same pair of comp locks. 12 came out at 1.954 1 was 1.952 2 were 1.960 1 was 1.962 So effectively these were coming out at ~+.075 installed height, although the machining on 3 of them was less than spot-on. I called Comp & explained to the tech support guy that if these are supposed to be machined at +.075 that they should at least state it in their catalog. When I mentioned that 3 other retainers all came in at 1.88, he stated that "you can't compare these to other retainers etc etc. & that it depends on the spring...yada yada which I politely called BS on , in other words, we don't have a problem, you do. I mentioned the sloppy machined height on 3 of the retainers, he seemed completely OK with it, offered no suggestions or resolution. The guy was polite but really didn't seem to think or care that there was a problem. Anyone had a similar experience with Comp?? I'm really getting fed up.....

We seen discrepencys similar to this and it end up being the wrong locks.The groove location on the locks,the angle must be correct(10* locks,10* retainers) as well as valve length and valve groove location on the stem.Also make sure the lock is seated to the valve and retainer completely.Have you measured the retainer thickness at the spring seat area? .

a stock retainer is 7* most titanium are 10* double check locks
all parts are sold as is, all parts are considered used no warranties or returns paypal/check/money order, shipping is from zip 02891, buyer pays paypal fees 24% IRS 1099A plus 3% of part price, check/money order preferred site is not monitored 24/7 there might be a delay in response

i'm now using tool steel retainers & i was more concerned that they don't cover the spring as much as the titainium retainers i swapped out. but apparently this is correct.
Did your installed height change too?
i went to a taller spring so i can't say for a fact that it did.

One thing I found out when I was switching to a solid roller. There is no industry standard on locks and retainers. One companies +.050 retainers or keepers may be the same installed height as another's standard height piece. Dave
i learnt this the hard way too. never mix Comp Cams & Crower locks & retainers & lash caps. one of the tech guys at either one of these companies, came to work still hammered from the night before & his eyecrometer wasn't set on zero before he made the call on the final measurements. 10* @ one company is not 10* at the other, & lash caps are not interchangable. i only buy comp cams stuff now, the girl behind the counter is hotter than the Crower agents.

I have found the same thing. When you buy new retainers or switch brands of retainers there is only one way to find out what height locks will work and that is try them. Like stated before you can buy a +50 lock and it will be the same as someone else's standard lock.

Just an update, I figured that using a Comp 630 -.050 lock would bring my installed height back down to about 1.900-1.905. Think again! Instead I struggled to get my height back up to 1.890-1.894 by having try multiple combinations of lock pairs on each valve. A royal pain. One lock half would pull the height down to 1.870 (-.083) no matter which other lock half or retainer I used it with. If you've ever wondered why valves sometimes mysteriously drop? Had to buy additional locks from comp to get the height even close to what these are advertised to be. Again, inconsistent machining makes me question why I still use their stuff.

The problem with valve spring retainers is there is no industry standard in regards to the height location. As we have all seen there are differences from one manufacturer to he next. Until someone like the SAE comes up with a standard, it's what we have to work around.
