thicker head gasket and other mods?

[rov716y]

i have read somewhere and cant remember if it was petrol or diesel about putting a thicker head gasket on to lower compression rates then upping the fuelling are air flow greatly to get more power. speaking to a friend he says that doing this would make my aaz a biatch to start when cold and not worth the gains!

i have moded pin in pump, got a k24 turbo to put on and intercooler. got a manual boost controller.  before these go on will get an egt guage boost guage and a oil temp guage

is there any other mods i can do apart from what i already done to help me on to 150 bhp+

Don't do it.  It doesn't lower the compression significantly, but undoubtably has a negative effect on the turbulance in the swirl chambers.

so no to thicker gasket!!

just enquiring what else can be down for more power
