Whats the biggest Valve size i can go?

really !!!!

the 1.6 head can fit on a 1.8 bottom end cant it? what hp should i be aiming for then?

should mention that im going to deck the head to raise comp JUST A TAD

Go to 11:1. That's what my 1.7 has got. Don't bash 5000 degrees of ignition into it and it's fine. (BRAAP!)

You can bump up the comp with high crowned pistons. That's what mine's got.

the head needs a skim anyway so i thought i may as well deck it cos i dont wanna buy pistons.

if the 1.6 head fits on the 1.8 bottom end i was thinking about getting a 1.8 bottom end and working that and putting the worked 1.6 head on it
