I found a ton of them on eBay with free shipping for alot cheaper and they fit your model year. Look at this on eBay:

MAZDA TRIBUTE 3 & 6 2.3 DOHC CYLINDER HEAD

http://bit.ly/WoUPEA

 

I just ordered all the intake valves with valve stem seals gona do it my self hope it works. do i have to replace all head bolts and crankpulley bolt ro just reuse them.
thanks...

 

Head bolts can be reused. Alot of people replace them just for good measure but they should be fine. Crank bolt should be replaced.

 

i was takeing off the valves on the head you know those little cups for the valve adjustment for the intake and the exhaust i tipped the head over some fell out and now i dont know which is which. what do i need to do?

 

I see #s on the inside of them

 

The numbers are the shim sizes for adjusting the valves u need a set of feeler gauges to fit the shims in the correct spots. Once u get the valves assembled install the shims in and bolt the cams in then use a feeler gauge to figure out which ones are too tight. I'm not sure what the gap is supose to be but I imagine u can google it to find out. U will have to remove and I stall the cams a few times to get all the shims in correctly.

 

I will get the valve clearance from the dealer on Thursday when i pick up the parts i ordered. do you thing it will be wise to replace all the exhaust valves as well?

 

do i adjust the as in the firing order like 1342

 

If the valves look ok I wouldn't change them. Just make sure they slide freely. Adjusting the valves doesn't require u to do them in a firing order. They don't have to be adjusted in a particular order.

 

I can't find the head bolts specs for my mazda3 2.3L 2005
