A late reply but i'l give my input anyway. You ideally want a head gasket, head bolts, (i don't think anybody does uprated 1's yet) because you can't really go stud and nut as the lifter's are 2 close to the bolt holes. I'm having some uprated bolts made, so will have a few set's soon. Cambelt and tensioner. Oil Filter. I have a Gen head gasket and bolt set, brand new sat here if anyone requires.
