                you Ford guys scare the shit out of me sometimes

                edit: Try giving those bearing sleeves a little heat therapy with a torch and freeze the bearing before pressing in. Makes for a nice smooth fit and you don't have to worry about bending your table vice / redneck press :wink:

                  Heh. I actually do, works great for packing wheel bearings too. Great versatility.

                  F**k specialty tools. Sometimes you have to make do with what you have, and in this case I had a great idea and some Grade 8 all-thread, 5/8 Nuts, And washers!

                  (Side note; I can always change washers for whatever diameter bearing I may be packing/pressing.)

                  Just wait until you see my redneck tire machine!
                  Heh..

                  @doc watson, I HAVE to ask why it is you're going with those old SMOG compliant 2 barrel 289 66 heads? :tremble:

                  Don't let the 54cc combustion chambers fool you, even the GOOD M-code Non-SMOG 289 heads flowed like crap, your J-code heads flow even worse & neither were ever intended for burning the unleaded fuel we use now days man. Those old school heads DO NOT LIKE the new unleaded pump gas. Without MAJOR valvetrain work done to them, I'm almost certain you'll end up with scorching valves, fouling plugs, burning pistons, or even lifting your headgaskets purely from spark knock/pre-detonation, and unfortunately, There is no amount of retarding the timing advance curve, changing out plugs, or re-adjusting spark gap will help you prevent this & it'll take alot more then just simple porting and polishing my friend.

                  That being said; I'd ditch those heads and start looking towards a new aftermarket set of fully-dressed 289 heads, or maybe even a used set of GT40P heads. They would save you money, time, elbow grease, and perform much better and efficiently in the long run.
                  (Not to mention, gives you a higher ceiling in case you ever to swap for a higher lift cam.)

                  Don't get me wrong, If you can manage to successfully grind off the SMOG humps, then do porting, polishing, screw in studs, valve grind, seats. retainers, springs, rocker arms & get GT40 valves installed into them, Then yeah you can make these heads become little monsters. But why the hell would you do that? Lol


                  Another pro engine builder tip as a friendly reminder,
                  289's have the steam holes directly above the bore, towards the lifter valley. 302's have them off to the side a bit. You're going to want the steam holes to match up again, so just take a head gasket and lay it on both the block and head and use the gasket to either drill a matching steam hole in either the block or head. Just make sure the holes line up & you're all good.

                  Keep up the build man! I can't wait to hear that 5.0 fire up for the first time. Hopefully my advice was helpful to some relevant extent. :beer:
