You may have to source the items individually. Most auto supply houses will have or can get them although you may have to go to several. On line is another option.


A bare bones hone and ring job would be oil pan, head and valve cover gasket, manifold gasket, standard cast iron rings, main and rod bearings. Probably a good job the replace the valve seals while the head is off. Depending on cylinder wear this is not going to run like new and if there is damage not even feasible.



New timing chain kit includes, chain guides, tensioner and cam/crank sprocket with gasket.

Have the head rebuilt with new guides and seats, but this will cost more than all the parts mentioned above.


Absolute best results would be to overbore and replace with oversize pistons and rings. Here you can use chrome or moly rings for longer life. Again much more expensive but you have basically a brand new engine.

Appreciate the information I am gonna try to source the best parts I can
