Cam gears if heads been resurfaced?

[DsMWookie]

Do i need them ....I am wanting to rebuild the engine and if the head gets resurfaced does it need cam gears to compensate for the changed mechanical timing?

How much are you planning on taking off the head and block?

As long as you don't shave off over what the maximun limit is, the hydrolic tensioner should keep the belt tight.

You are correct about belt tension, but it still retards cam timing.

If he's just resurfacing, its fine. If he's decking it (say it was warped) think about a thicker head gasket!

assuming that the gears are 5in diameter, takeing .020 off will cause a change of about .45 degree's. Thats small enought that you can't repeatably change the timing by that much. so i wouldn't worry about it.

The head isnt warped on the car now and fine...just know the shops resurface them when you get them rebuilt......so the end result is I could get away with out adjustable cam gears?

Def, they only take a very small amount off on a resurface. Thats if it needs it. If its warped and they really have to goto town its different. But you can usually try a thicket headgasket in that case.
