Holden VZ HBH heads to do or not to do

[simsy25]

hey guys, ive got a problem in my v6 svz, either cracked heads or blown gasket, ive been told a gasket kit is 700 and 300 to check the heads, is it better off finding another engine and replacing it or have it fixed...any comments on cheaper parts (non Genuine is fine) is appreciated...and also is it possible to put a 10HBA engine in without replacing the computer??...

hey buddy before you go that route try too to put some sealant thru your cooling system, if youve got a supercheap up there... they got a bottle off shit , looks like copper colour when shaking, try this it might do the trick..
