I have done this many times on small block chevys, is it a similar procedure for the viper engine. Any tricks i should know about
It's not that much different than a small block engine. Just be careful not to over torque the bolts. I aould ARP the heads while you are doing that also... be careful again not to over do it. You can warp the block and also make sure you blow out the bolt holes of any water that gets in there. Keep your working area on the engine clean and if you have stock heat shield... be careful of those too... very sharp edges that can cut your fingers.

I'd add, while the heads and intake are off, you should check the heads for deck flatness and have a good head shop check the valves and give the heads a once over. I had one bent valve and one bad valve guide in mine, I was glad I had them checked. If you want, it is also a good time to change the thermostat, and maybe port and polish the heads and intake. Wanna powder coat the intake a differnt color? Now would be the time. Also, depending on the miles, new lifters might be cheap insurance.
I just put mine back on with a set of Cometic gaskets. I sprayed both sides with copper spray and no leaks. Be careful when putting them back on because there are many things that can scratch the surface on the heads.
The Cometics can be ordered in different thicknesses if you want to change your compression a little.
Also while they are off bite the bullet, send them to Greg Good and pick up some major power.

If doing the ROE car, it is easier than doing a stock car. If doing the ACR, it is still easy!
2 hrs to get them off on the ROE. 2.5 on the non-ROE.
Good luck!

This is for my Roe GTS.Im planing on installing the Roe heads and port matching the intake
The reason for this is the white smoke im getting under deceleration, i think the valve guides or seals a bad.
At wide open throttle there is no smoke, its only when i let of the peddal

vegaviper:
see my answer to your other post, this may be premature. Check the the hoses that were indicated in the last post, if they are oily, that is the issue.
JD and j Dawg:
I would like to wager that you cannot have the heads off of a car in two hours. The time starts when you drive the car into the garage and it has to be a car that has not had heads and headers worked on previously. This is also one person working.

Best advice - Zip Lock Baggies to keep all the correct pieces and parts together. Also, remove air box for easy access to passenger side head.

Jack, i did and there is no oil in hoses or the air box. The catch can does hold the oil and i drain it often. The car has never done this before and the white smoke when letting off the gas is alot

Jack -
I'll take the bet. It takes me 3.5 hrs on my DLM car to get the heads off, but when doing a recent creampuff converstion, it took us 3 hours from hood removal (1st thing we did) until having all 10 pistons out. a clock check when the heads were off showed 115 min from start.
It isn't that hard. Or complicated. And on a ROE set-up (which this one was), it takes less time than on a stock set-up b/c the blower assembly comes right out.
PS - No lift for this job.
PPS - I ain't bull-shittin' .
PPSS - I have a friend that I witnessed do a clutch job on a viper in 45 min. the tranny was out 15 min (almost to the second) from the time the car was put on the lift to the time i was staring at the tranny on the floor. He was done w/ the clutch job BEFORE I was done with the VEC2 install I was doing on someone else's car in the next bay.
These cars aren't that hard to work on.
I'll take the bet. With pleasure.

My car does have headers on it and had modified heads on it last time I tore into the car. Last time I had to take one head off, I had the intake, head, header, oil drained and oil pan off and a piston out in less than 2 hours.
The first time it did take a little longer, but nothing special about this car's motor.......it is just a small block with 2 more cylinders to me.

Jack B - A second ago there was a $1000 bet you were offering??? What happened to that wager offer?
So Said JackB (before editing): "I have $1,000 that says you cannot have the heads off of a car in two hours. The time starts when you drive the car into the garage and it has to be a car that has not had heads and headers worked on previously. This is also one person working."

I suppose one minor detail needs to be addressed: I've done head jobs w/ the hood ON the car. In this case, though, I took it off with the help of a 2nd set of hands. So I'd still take the bet w/o having the hood off but my preference (and for the sake of my back) would be to allow the hood to be removed.

I did but it wasnt a dynojet. It was dyno dynamics brand. Car seems pretty strong. We will see what kind of mph it traps when they get the tracks cleaned up around here.

I heard that once the heads are off you have to bolt a plate on the block to keep the cylinder sleeves from moving ??? Any comments on this.

If you'd quit breaking off bolts in the heads, it would take a lot less time! How many do I have to extract now?!?
in/lb and ft/lb are different!

they are more of a yellow-ish... but with all the dirt, i guess you can't really tell.
I'll change it just for you. In fact, to heck with the whole signature!

take a wild guess. well it doesnt even have to be a wild one. It was the one thing I had a gut feeling about the entire time.
VAVLE SPRINGS.
Replaced them and had Greg Good finish out the heads to Pro Stock status and all is well even with the VEC2 on the car. The car tuned up really nice and runs strong. I told Sean I would make a post when I get back to a dynojet to get some numbers on the car
The 10.19 at 135 and 620/690 was on the old mising setup. Those numbers are old and slow.
Take care
