Im new to the whole 4g63 thing and I just purchased a 1992 Galant Vr4 number 456/1000. Now Ive owned a Twin turbo stealth and I currently own a VR4 3000gt. And I have done quite a bit of work on cars such as clutches, transmissions and complete motor swaps on my 3000. But I think my Galant has a blown head gasket or a cracked head... How hard would it be to swap a head or change the head gasket? Does anyone on here know of any good mechanics in Roseville/Sacramento area that are good with these cars?
