I'm doing a forged bottom, vortec build,a2a,headers, 67mm turbo ECT. I have the stock reinz head gaskets and ARP head bolts already. Would it be worth it to go with the cometic gaskets? I've seen good and bad about cometics......Dont see much bad about the stock reinz gaskets......My motor was rattled so bad by the last owner that it broke 3 pistons and bent the crank, yet gaskets were still fine. I rebuilt it all and ran 20+ psi on a new set of stock reinz gaskets and they looked perfect when I pulled it apart to do this build......Thoughts? Thanks guys
