Not too dissimilar to mine then really. What cams are you going for? Also what engine management?
Exhaust system wise id personally look for something like an x14xe or x16xe 4-2-1 system. It will help with torque (4-2-1), the lower bolt holes just need some fettling and they dont sit so low to the ground generally. Use an x16xe sump and shortened pick up pipe. The Ashley exhausts are quite generic and just 4-1 unless you get a custom one.
I will be porting my head myself, concentrating on the short side radius in the ports and the valve shrouding.
