SDPC heads ? I see they're a sponsor here and was wondering.....
Looking at SD9063C and need to know spring pressures....These will be used with a LQ4 short block and a carburetor.
Cam is a CompCams custom ground using LSR lobes 239/247 at .050, 110/106. They recommend the Spring kit 26926TS-KIT.
IF they are, I could save a few $$$ buying the heads with spring upgrade Vs. piecing together used heads and a spring kit.(LS3 heads are on everybody's want list
)

I thought the ls3 valves were too big to work in the 4.00" blocks. I'm thinking they are 2.200" valves... BUT I may be wrong. I have never looked @ any info on the ls3 stuff.
