Lets take a look at the PAC 1218 Beehive Racing Valve Springs for the Chevy LS engine, 6.0 4.8 5.3 LS1 & more. the spring specs are down below.

I picked this set of springs up for the SS2 Camshaft that we installed into the LS 6.0 that we have been building here on the channel. they should do well with the 799 LS heads.
