Reinstalling Heads

Rosco · 07-08-2005, 07:42 AM

Well i just got my stock heads resurfaced, due to a blown head gasket and blown instake gasket as well. I am about to start reassembling the top of my motor, and I was curious how how I should set the rockers? Stock lifters, stock pushrods, stock springs/valves, and stock rockers. I removed the pushrods to remove the heads, but the lifters, and the rest of the heads were never disassembled. Just the rockers were loosend enough so i could slide the pushrods out. Im not sure if i supposed to start at TDC or what. This will be the first time I've ever adjusted the rockers. thanks alot everyone

its kinda hard to explain in short words. Do you have a chilton manual? I found it very helpful because it goes over it in detail. You can get one at the auto parts store and it has the torque specs you need, etc.

Which Rockers Do You Have If There Bolt Down Rockers (thats When The Bolt Screws In To The Head) Then You Just Bolt Them All The Way Down Torqe To 15 Ft.lbs.,,,,,,,,if There Stud Mounted Rockers (the Stud Is Sticking Out Of The Head And Tightens Down A Nut) Then Its A Little More Complex......theck Some Net Sites They'll Have Some Info........good Luck

Yes, I actually have a chilton's manual and a helms manual. They are stud mount rockers. I also just got my heads back from the machine shop, and he told me that the drivers side was off 5 thousands, and the passenger side was off between 8-9 thousands. He also told me not to use a gasket between the front of the lower intake and back of the lower into to the block, to instead use silicon gasket maker and make sure it's o2 compatible.

Ya, don't use those gaskets at the front and rear of the manifold. I had one pop out on me before. Use high temp silicone. Squeeze a real thick bead along the front and back of the block where the manifold sits. Let it sit for a little while to get tacky before setting the manifold on.

You'll need to find TDC on #1 to put the distributor back in. Then it's a matter of adjusting the valves. Plenty of info on the web on how to adjust valves. It sounds scarier than it is. Good luck!

If you have the stock heads, then you have pedastal rockers (non-adjustable).
