i have a b20b with b16a head, i just replace my head gasket again, and it still leaks...any suggestion to whats my problem?

i got the swap in maybee 2 months and went through 2 head gaskets, and a 2 pairs of axles. man i hate cars...
b20b,b16a head,sir intake manifold,toda camsprocket,ctr TB,gsr tranny,jdm 4-1 exhaust manifol,arc airbox

 

check the deck of the block and the head to see how flat they are. thats one of the problems about having 2 different motors turned into one there is a chance one is not flat and can throw some oil.

 

thanks a lot rainforest!
