after I got the cylinder head which uses an additional valve which they call the MCA Jet valve

does anybody know the difference 4g63 cylinder head MCA Jet valve SOHC 8 valve and cylinder 8 valve LT, should i have to block it or just activate it?

if anyone knows the difference 4g63 SOHC camshaft turbo and NA because after my attention there are similarities between the camshaft turbo and NA

thanks for your info........
