from memory, the 18R chamber in the head does not cover the entire piston area - i think there are a few tight squish areas away from the valves - so do some measuring before bolting head to block.
Even if piston/head don't hit, using uneven squish areas to lift compression ratio tends to increase detonation/pinging.
also, the whole front of the engine is different - timing cover, timing chains, dummy (half shft) to run dizzi & oil pump, water pump, etc are different between 18RG and 18RC
Would be easier/safer/cheaper to find an 18RG head, give it a quick-and-dirty reco and bolt it up. You'll get better breathing, cooling, power etc than the 18R.
