Malossi head gasket

Having recently purchased a malossi 210 from sip, i have ported the piston and cylinder and matched the casings ,the end result being it goes like f*** even with the standard carb. But just a quick question for anyone out there who might be in the know, can i run it without the head gasket provided. ps i have the sip centre plug head .[:roll:] [:drink:] [:dance3:]
