Was looking at doing a cam kit on my 2001 z06. Looking at using some btr springs with a 228r cam I have. What would be the best springs for this cam? The .660 platinum springs with titanium retainers or the .650 max pressure? I want the absolute best springs. Lightest, longest lasting, and easiest on valve train? Which springs are for me?

look at some pac 1218 or 1518 springs,they work with the stock retainer .

If you want something easy on the valve train then start with the cam lobes you choose. The 228r uses CompCam XER cam lobes which are hard on the valve train. IMO, go with some Xtreme (High-lift), or LXL lobes if you want better valve control an valve train life. You also need to know that with less aggressive cam lobes that offer better high rpm valve control you will give up some power over more aggressive lobes like the XER's. It's all about where you're willing to compromise.

The best spring depends on application and net valve lift. For cams under .580" lift I like the beehive springs, like the PAC springs that were mentioned or their 1211X springs. For cams over .600" lift I prefer dual springs for maximum durability.

The Platinum springs work best with stock rockers as they have limited open pressure. Too much open pressure when using stock rockers can cause valve tip damage.

The Max Pressure springs were designed for the heavier mass of roller rockers.

On applications over .660" lift I like the PAC 1207X.

I hope this helps.

My main thing is not wanting breakages. I knw pac has had quit a few. And the btr springs have zero failurs still? The 228r is close to .600 lift and might be to much for a beehive?

Correct, the Platinum springs when used with less than .660" lift still have a zero failure rate.

Since Brian didn't come right out and say his springs are the best, I will. Brian's springs are the best on the market.... Seriously though put the Platinum's on it and be done with it.

No sense in overkill with 660 lift springs...longest lasting and lightest cant be achieved...have to go somewhere in the middle to get both benefits...that being said I've always heard nothing but satisfaction from people with the Brian tooley springs

I really meant lightest double spring. As long as the platinums don't eat up valve tips and aren't to hard on valve train i would like to go with them. Zero failures is awesome. Will stock lifters last with the double springs? Might also start looking into a cam thats easier on valve train also

I was running the LS7 lifters and was getting a pretty good tick at hot idle. I changed over to BTR SLR lifters and its gone. I have inspected my valve tips a couple times and have not seen any problems. I am running stock rockers with the Comp upgrade. Also running Brad Penn synthetic blend 10w 30. It has the high levels of Zync in it.

My cam specs are 242/250 .621/.595 XFI/XER lobes.

PSI Beehive's will work for your application.

I just don't know much about them? I would love a proven single spring, but don't know if psi is known for breakages or not?

if youre worried about breaking buy the btr springs, a dual might be a little overkill for that cam but theres nothing wrong with it. Im one of the many people with btr .660 springs without a problem, great product and great customer service.

I recently tested a set of the LS1511ML springs and they didn't deliver the advertised pressure. I was shocked based on their reputation. The PAC 1211X did match their advertised pressures.

I agree with this recommendation. Many overlook PSI springs, but they a top notch spring.

Good reputation or not, single springs just flat out scare me. At least with the duals you have a bit on insurance on not dropping a valve.

You should get good long life out of the platinums Brian sells with the lift and lobes that cam has.

I'm running his springs with a .631.631 cam and they've been excellent. Really REALLY hard to best his customer service as well.

Tooley or PAC> everyone else.

Once you have bigger valves (thus heavier) yeah, I agree with you on the safer, but to what degree that is debatable.
Keep things light as possible and beehives have been proven to control harmonics better and to produce a few extra ponies.
Most failures are due to improper install (just drop in) without paying attention to installed height for proper pressures.
I'm a fan of stock size valves and I never had an issue with singles running from Comp 918s to Pac and PSI. I'm partial to PSI.

Z, I completely agree. Singles have just never been an option for me though.

I'd imagine some Cartek, AI, or WCCH stock ported heads with LS6 valves, and a set of PAC singles with Ti retainers would be really friendly (stable) over 7200 if need be.
