224/224 weber roller cam. Comp 918 Springs?

[20psiofevil]

I ran yellow ls3 (have 12 for sale) in my previous setup which was .520 210/218 112* cam. If the 918's fit than the yellow ls3 springs are a good option up to .550 lift. This is what some are going to in the ford v6. Think they are very similar to the 918's. http://www.summitracing.com/parts/hrs-98432

Dang, just looked at those pac 1203's and they supply some insane seat pressure. Is it a must to run a ss valve to keep from snapping the valve? I thought the 918's were high for my valves lol.

Thanks for the other suggestions, But I want to stick with what I already bought. I hope The vavles I got on my champions work.

Valves will work, make sure you get a good set of pushrods on there. Also, get a hold of some comp 885 lifters or go solids.

How about morel lifters and push rods?

High-intensity lobes require aggressive springs

Those aren't going to work with the open pressures the 1203 springs will generate. They will flex.

the 1201X is the strongest drop in and will work, the specs on their web site are wrong they are stronger than the 1201 and have a higher rate I use them with some VERY aggressive cams

Just got a call from the machine shop and he cant find retainers or seals that will work with those springs. Anybody have any Ideas where I can get pieces?
