chunhoo,

Normal ppl said change head that referred to changing from 8v to 12v or
12v SOHC to 12v DOHC.

For your case, i think it's best for you go for 4G61/4G92/4G93 (all non-
turbo) engine transplant

The cylinder head is the part of the engine that contains the valve train
and camshafts.

For your case, there won't be any improvements because the 1.3 and 1.5
proton engines share the same head configuration. 12 valves and single
overhead cam.

The 1.5 DOHC 4G91 head will not fit on the 4G13/15, sorry.

For more power and reliability, I would suggest a complete engine
transplant. A complete 4G91 transplant will give you roughly 115 hp.
