mdxj35a

Question to everyone, I have a j35a5 engine in my 06 mdx but it's crapped out at 333000Kms. So I'm thinking of swapping a j35a8 06 RL engine in or possibly a j37 but I do not know if the bell housing patterns are the same. Also if I do a j37 from an 07 mdx, what heads would be best to use. I've read the j35a5 uses type s j32 heads. Future plans are an m90 charger as well.
