i heard about the hf motor doing 14's in the 1/4 mile with just putting the 16 valve head and the other little things

Q: how is it possible if the hf block has 8 groves on the piston top how would the exhaust valve pass wouldnt they hit with the pistons has anyone done it ?
cause i just bought a crx hf and i have all the parts to do this swap but i dont want to mess the head up by putting it on the hf block
any info would be appreciated
