Well, you are going to need to swap out the pistons as well, you might as well just swap in an entire Si motor. The HF head only has 8 valves and the HF pistons only have reliefs for 8 valves. This means that putting the Si head on a HF block would result in bent valves.
Just swap the motor out.

exactly. Also, if you wanna have some extra power without hasseling with VTEC, you can use a D16A6 (88-91 CRX Si) engine block with a D16Y7 (96+ non-vtec sohc 16-valve) cylinder head. The Y7 head has larger valves, and combined with the A6 domed pistons, you get 10.5:1 (somewhere around there) compression. Bolts right onto the A6 block, no VTEC to worry about, and will give you a very noticable power jump over a stock CRX Si engine.
