were all crx hf's in 1990 16 valve or no ? cause i got and hf and the valve cover says 16 valve but i looked and was told that hf motors were 8 valve is this true???

what the the head number stamped on an hf head and a DX head ???? so i can check the number

 

ok yes all hf's were 8 valve.....the head stamp for the dx/si head is pm3....whats the engine code on your block??

 

the block code says d15b6 and the head code says pm9-5 so if its all stock hf then they just changed the valve cover before i had the car
