TRD Gasket, Stock 4age

[carina4age]

Hey,

my 16v bigport blew headgasket few days ago and i want to swap it to .8mm trd head gasket to have little bit more power. My engine is completely stock but im going to get the head resurfaced. I just want to know is it possible to use that 0.8 trd gasket with stock engine?

yes it is possible to use it on a stock engine. The issue might end up being that while the head has a nice fresh surface, the top of the block isn't. This may cause less than adequate sealing. If you can get a straight edge and check it and find no high spots(or low spots) in the top of the block, then it may seal properly

Yes, i will check top of the block. Do you know what is the correct tightening torque for that gasket? I have new Toyota OEM headbolts. Also, will the timing marks line up with thinner gasket?

Use pattern in FSM. TRD recommended 48ft/#s(650±20 kg･cm). I recommend doing it in 3 passes: 25, 36, 48

New bolts won't be as smooth, thread & head, as old so you might actually be tightening it less then before.
Yes, thin gasket will retard the timing, head cut even more. How much? IDK.
Good luck.
