I'm still new to the whole Honda world (convert from DSM after $3500 was spent in 2 months to fix my '97 Eclipse GS and it still wasn't working right) and I've heard that for block series that some parts are interchangeable. engine has about 200,000 miles on it but the block is in good shape and since it's an in between car I'm going to just rebild this engine but I've been having trouble with the valve train. I've found lots of aftermarket support for the D16A6 head but I've still yet to find anything for the D15A1 in my DX. Are there distinct differences in the D16 and D15 heads that prevent me from using D16 parts on my D15? If so where can I go to find some good parts for my head?

Oh yeah and I already did a search and didn't find anything specific to my issue

 

same parts..

Honda actually now sells d16a6 valve train parts for the d15. They are all interchangeable. At one time I believe the spring rates were different, but now if you ask for d15 valve train parts they will give you d16 parts. Did I repeat myself? myself?
