I was wondering if there is a huge difference between vtec and non-vtec valve springs? Because my b18b w/b16 tranny rev's high and I really don't want to throw a valve. I'm gonna either way get new one's but I'm curious to know. Also has anyone heard of a f22 in a civic or crx? I was looking threw the new honda tuning and in the back was a spread on Bisi Ezerioha!
