What valve springs and retainers?
I have a XER287HR comp cam I am putting in a lq9 with 243 heads Comp doesn't show what springs to use with this cam. any help would be great. Also if i run this cam straight up will I have enough piston to valve clearance?
Cam specs are 605/609 238/240 on a 112 lca. Oh and what lifters?

The all new PRC valve springs are a ground up replacement to the gold/platinum spring kits that's been around for several years. The PRC .650" spring kit will easily handle what your looking to do & was designed to provide a longer spring life & resist losing spring pressure. The spring kit is priced well under $300 & offers springs, titanium retainers, seats & seals.
If your wanting to go single springs & don't mind changing springs more often, you might checkout the PAC single springs. We sell them as a package with free new valve seals for $150!!

Set of PAC 1518's will do the job, direct drop in replacments, some people prefer doubles, but they require a seat and seal change. You have the PAC 1221 and 1521 if your looking to go with doubles as welll as the PRC's and Patriot golds.

And very few of us have he ability to test on a spintron, so we generalize based off of experience.
I would still go with a set of 925s or 926s and add the tool steel retainer.

Patriot extremes would work nice, 155 pound seat pressure and take 660 lift plus very light retainer and good locks. Full kit for like $275. Throw a new set in every 15000 miles.
