Arouse the DAMPFHAMMER!
The K24Z2 has an 10.5:1 CR, which is good. About the RBB head (same on the K24A2), which has the performance roller rockers and camshafts on board. The 36 mm intake valves (+06) are not necessary, but the +06 cams would be a little advantage. I wouldn't use the RBC camshafts, you will loose most of the torque and see their advantage just at the redline.Ok I’m about to slap together k24z2 block with RBB head and RBC rocker arm and camshaft should I slap to together need opinions
Definitely check out that R40 style block: deck height, valve relief depth, oil and water interfaces. Not sure if this is a direct bolt on approach.
