Comp LSR Cam
#25
Brian I'm glad you found this thread and are spreading the word!
Take it from Brian guy's he knows what he is talking about, we sell his springs also for this reason.
I see guys get the LSr LSL thing mixed up all the time too as LSr is not a family of lobes just a line-up of cams from Comp.

I'm still on the fence about this cam, trying to figure if this would benefit me as far as cost vs gain.
I spoke with Brian about it..the GM article is pulling strong numbers..question is if mine would do the same.

Really?
I apologize if that was the case. In the past 2-3 months we have just exploded with business. We had over 25 cars all having extensive modifications performed to them over that period and just got about 10-12 out the door last week and the week before only to get 4-5 more in this week and 4-5 more in next week.
We are really blessed with business, but it really gets hard to remember all the screen names and real names that call me everyday. Waking up to 25+ emails, 10+ PM's and 8-10 voice mails each day is great, but at the same time very draining! Enough complaining though lol!

I do have a couple of pics of stock LS2 heads run with a LSr cam and 26926 springs, although the quality isn't the greatest. These were from a otherwise stock C6 LS2 using Comp cam, lifters, pushrods, trunnion kit and 26926 spring kit.
The valve tips should be flat and smooth, just like stock. With too much open pressure they will start to pit, look uneven, and eventually will stop rotating and have trenches cut into them.
The things that will help prevent these issues is running .630" lift or less with stock 15 degree rockers, running 400 lbs or less open pressure, running stock locks which allow valve rotation, and any type of oil additive that helps flat tappet cams prevent wear. Such as racing oils with zinc, etc.
Obviously running roller rockers will prevent this wear, but the heavier roller rockers need increased spring pressure and increased pushrod rigidity.

I know it's an old thread but still relevent.
Interesting enough I have a set of LS2 243's pulled from my Corvette with 10k miles. The valve tips look identical as thee one's you posted. All was stock except for as set of 26926 springs and LSR lobed Comp Camshaft.
