yes you need to remove cams to pull head bolts
Yes you have to pull the cams to take the heads off. Just mark everything and you will be good to go.
Thanks guysyes you need to remove cams to pull head bolts
With 15 psi showing you should have known something was wrong...cats had to be melted to cause that much restriction and inlet temps probably skyrocketed. Bummer. :nonono: My advice would be save up for an aluminator.....if you can't afford to fix it properly then you can't afford to blow it up again.... There's no such thing as a cheap rebuild anymore with the cost of all the one-time use bolts, plus bearings, rings, machining, gaskets, etc... A take-out short or longblock might be the cheapest. Also check with Ford on a stock replacement shortblock. I was looking at getting a 5.4 3v shortblock rebuilt a few years ago and it turned out a brand new one was only around $1000 with core (didn't matter that my block had a window...), a Coyote is certainly gonna be more but I was surprised how economical the factory was in that case. PM FORDSVTPARTS (Autonation, formerly Tousley) on here if you want the best deal on that, an aluminator, or just your rebuild parts for the best deals you are likely to find.
There is always a way to go bigger on a budget. Doesn't mean it will immedistely break.
It just means you won't accept the idea that more $$ always equals better. Often times it does not.
Good luck and keep at it!
Op, I used Blazer's writeup when I installed Billet Oil Pump Gears and FRPP Exhaust cams. I would also recommend you get a one month subsrciption to http://www.helminc.com/helm/homepage.asp?Style=helm . This is the same resource Ford Techs use. A valuable tool during the build, I used it as well.
This is what I bought:

how low was the compression?
do your best to measure deck height on each cylinder to rule out any bent rods.
You should've mentioned something, I've had a plugged cat on a couple cars before that will show bad relative compression on an IDS and also on a manual compression test show an issue. Disconnect the exhaust and concern goes away.
Lol I love hitting limiter, makes me feel alive. The limiter was set at 6900 though, so it's not like I had a 7500 tune. Still doe, dem pistons shinin.Congrats on it not being hurt. I watched your video and cringed a little when it sounded like you got on the limiter in the burnout. I have a friend who builds racing engines and he warned me a long time ago that doing that can actually knock the bearings out of a motor. I was listening thru crappy headphones with crying screaming kids in the room so forgive me if I heard incorrectly...
Since you have it torn down why not get a forged rotating assembly?
Yes it is a 2k difference, you won't have this problem that your having now, you won't have to worry about blowing up the motor and having to do all this over again.I would love to, but it's realistically a $2000+ difference. I'm in my car for $13k including the supercharger, the car itself is worth about $8k. I'm at the point where I just want to keep things cheap and still be able to walk away from it if shit hits the fan. I am a "young", very single homeowner that doesn't really make a lot of money.
We're gonna need a bigger ring gap.
My guess is the rings expanded and cracked the pistons. Makes sense considering the situation.

I guess you could blow it up but it would be a lot more difficult.
