Right, so right now Vicky's engine is sitting on a stand, and we are in the process of replacing bearings and seals and whatnot, adding in the mustang dual exhaust, and removing the smog pump. We are a little stuck however on what to use to plug the holes in the back of the cylinder heads. We've tried 5 or 6 different bolt sizes to no avail, what has everyone else used? I did a search and didn't see anything, unless I'm completely blind.

Apparently you can just flip those "pads" around to cover the smog hole, and tighten them back down. I've got to do the same to mine one of these days.sigpic

I took the crossover pipe and cut that POS up leaving just the parts that actually connect to the block. Flipped them (putting the flat side against the block) and used some ultra copper (had it on hand) to make sure the seal was good and bolted them down tight. I did it in the car... so I had a bit more of a time getting at them... but with the engine out... it should be cake. Then you don't have to worry about putting bolts in those holed... just use the stock crossover pipe bolts and snug it all down good.

5/8-NC or cut and flip the stock pipe. I've done both, cut and flip is usually easier. Getting those bolts is hard enough, and usually the threads are so clogged up you won't get them threaded in anyhow.86 Lincoln Town Car (Galactica).

Thanks Everyone for the response!
This. Granted I have the money to do SOME upgrades, I really don't to spend money twice. IE I don't want to spend too much money on this engine, because it's coming out for something bigger eventually, and when I say bigger, I mean 351 strokerOriginally posted by 79lincolnlover View Post

Ok, so for the record, we used 5/8 inch soft plugs, and just an update, the engine is sitting back in the car, waiting to be hooked up.Parts Car (Scrapped ) - Vicky - 1987 LTD Crown Victoria: 17x8 Gunmetal Gray Coys C-5 wheels, 235/55-17 Falken Ziex ZE-502 tires. 79 LTD Grille, Taillights, and Turn Signals, Blue LED Dash Lights, PI Rear Sway Bar, 140 MPH Speedometer, Dual Exhaust w/ Mustang Headers.

Just finished taking the pipe off of mine and cutting the ends off, those bolts came out remarkably easy. Just gonna turn the "pads" over so the hole is facing outward and the flat part will cover up the holes in the back of the heads.
Also in case anyone is wondering the bolt head when you're removing the smog crossover pipe is 1/2".sigpic

I use a distributor tool to reach those bolts while the engine is in the car.
