mk1 motor work NA

well finding out i have a backwards 4AGE motor bugs me because everyne i know who has driven it says its not stock. well i would feel beter if i had built the motor and i dont like turbo and dont really want a charger so i gigured id get a blown block and rebuild with what i want ... but i have no idea where to get parts ... anyone have any blow blocks or parts they dont want or know where i can get them

need alittle piston help .. should i raise it to say 10:1 or lower it for alittle more power from a na motor, im planin on a cam and injectors and valve job new gaskets maybe a port and polish but thats about it
