there the 243 casting with the truck valves, same ones as in the 862, 706 casting heads, looks to be good for another 20 hp by the claims of the stock hp of the 07's 315 compared to 295.

not all 243 heads are ls6...a ls6 has the lighter valves and different springs

243s are on LS4s which are 5.3s, LS2s with stock valves

the heads flow the same as a 317 but just with a smaller CC
