Did you find the torque specs and sequence in the online manual? The procedure for adjusting the valves is in the same area. If it takes you less than 20 minutes to set the valves you are either very good or going to fast. After you think you have them adjusted properly rotate the engine by hand through at least 4 complete cycles and recheck clearances. Many times they will have changed due to sticking during reassembly. I use assembly lube (Permatex Ultra Slick) on everything that moves without threads, including a coat on the cylinder walls. Remember to dry torque the head bolts.

I found the specs thanks, I will get some assembly lube as well. I will make sure to recheck the valves thanks for reminding me about that I forgot about that. I feel confident I can do this with all the info you have given me, you are very thourough with the details, just hope this does the trick

Just got the head gaskets in the mail, going to get started soon. I just reread the manual and only question I have is when adjusting the valves it says to have the piston 1/4" past TDC, so im assuming that means to have the piston go down 1/4" after it reaches the top. I thought it was supposed to be set at TDC but after rereading I noticed it said 1/4" past TDC. Thanks

Manual is correct 1/4" passed TDC. This is to allow for compression release. Good Luck

Got a lot done today I spent a lot of time cleaning everything up, got it looking almost like new with the carb cleaner and 0000 steel wool, I cleaned the cylinder walls and applied the assembly lube, got the heads on but then realized my 1/2 inch torque wrench couldnt go less then 25 ft/ib and I needed 18 for the heads, I found someone I can borrow a 3/8 inch torque wrench from on Monday. One quick question how to I know when the piston in 1/4 inch tdc, do I measure 1/4 inch on a small screwdriver and mark it and stick it through the spark plug hole?

Just about that way. This one does not have to be that exact. I justbstick a screw driver though the spark plug hole and watch when the piston starts going back down. Rock it back and forth a couple of times and make your best guess.

Well now I have another problem, I got the correct torque wrench, I did it in 2 steps torquing half spec to full spec in order, I got the first head done no problem, on the second head just about done on the last bolt and waiting for the click any second then snap, the bolt snapped. I ordered another bolt and I'm going to have to find a bolt extractor tool somewhere, not sure if the bolt was weak or the wrench is junk, I cleaned really well. That's my update hope to get this fixed soon.

I knew something would go wrong ,it always does but if it turns out to be a $6 bolt and some fun removing a bolt then I'll be ok.

Be sure you are in the correct range for your torque settings. Inch pounds and ft. pounds are obviously not the same critter. I've done this mistake myself.:ashamed: Nothing on this planet is more fun than extracting a small diameter broken bolt.:eek:
