Well my head will be done today at the machine shop, it checked out good, and i had him install new valve seals. Well i know the trans had atf in it so i drained that and now gonna put new fluid in it. What weight do i want to run in the trans, quakerstate 5w30?? im unsure on brand but thinking 5w30. how about for the engine. i wanna run syn. but dont want it to leak after all the crap inside gets flushed out. what is my second best choice? mobile clean 5000 10w40??? im still unsure. next for the head bolts i know you are suppost to soak them in oil before you tighten them down? what weight, and i think i know where i can find the tq specs. thanks
