Would milling a B18C1 head .20 and using a Mugen Head gasket with my 10.8:1 pistons raise the CR to around 11:1?
Also when putting the ITR valve springs in my cylinder head, i take the GSR inner springs move them to the exhaust side, and place the ITR intake valve springs on the intake side correct? or should i just run the ITR exhaust valve springs on the exhaust side?


Thanxs for your guys help in advance!

i think you have that backwards- the exhaust springs ar ethe same as the r's. also the retainers you have in the car are also the same as the r's. so all you have to do is buy a set of intake springs

 

ermmmm i have both already lol so just swap out the intake side?
