First post, so please bare with me. I have a b18b waiting for a vtec head, but I want to mess around with my stock engine while I'm waiting around. What my question is, are there any head swaps out there I can do with my oh-so-exciting stock d15b6 out of my 91 Hf? I'm seeing tons of SOHC vtec's out there such as the d16y8/Z6. Is there any way to marry these heads to the smaller/weaker blocks? I know I won't set any speed records, but just curious to get into engine building and wanting to learn more. Thanks in advance!
