I used to have an Hf, so my friend keeps asking me questions about an 89 she's looking at getting. Blown head, bad clutch. So, I was wondering, (can't remember from my old rex days) will a dx head fit an hf block, bolt up, just use the hf intake manifold? Sencond, I have a clutch for an 89 Si sitting in my garage with about 8K on it. Told her it's her's if it would work... Will it? Thanks! I knew I'd get help from CRX guys/gals. You were always good to me when I had mine... RIP.
