No i didnt get a change to mess with it anymore i had a spinal procedure done that took me out for awhile long story short i got ran over in october 2016 by a lady that was texting an driving she went threw a red light and ran me over on my motorcycle been slowly getting put back together sense
Spitting out the intake or exhaust is timing. The cam is off timing or the ignition. Did you take the coil packs off the valve covers? Did you take them off the brackets or as a full coil pack assembly?
Did you make sure to put them back on the same side?
Being that you didn't seem to be aware of the timing marks on the rollmaster set, I'm willing the bet the cam is way off timing.

i took the coils off as 1 just like ive done in the passed so that aint the issue also the cam is in dot to dot so thats not the problem i did do a compression check and had 0 compression in cylinder 1

I wouldn't be so sure. You don't know what it is but you're 100% what it's not?
Let me ask another question. Which timing mark is it on on the rollmaster set? In other words which timing mark did you set the lower gear timing mark on?
.
You said you didn't think it was an adjustable set and it's been said it is. So it's very likely you have the cam timing off. Dot to dot with an adjustable set only means the cam is in time for whatever degree you set the cam at, and unless you're trying to set the cam at a certain degree to account for something, then it should be set at 0 degrees. Which there's a good chance it is not since it's backfiring/sneezing. When it does that, the ignition or the cam timing/firing order is wrong, or the valves are held open.
Did you check compression on any other cylinder?
Also you asked about pushrod length with 243 heads, if you have LS6 Z06 243 heads with the lightweight valves, they are longer, and you'll need a shorter pushrod. If they are 243's from a truck or a GTO or anything but a Z06 then you should be okay with the 7.400 pushrods.
thank you! its taken along time and im still not 100% got some nurological problems ill never be able to recover from with the headaches and sensitivity to certian lighting and other issues that continue to bother me but alot of recovery is about a mental state and beliving you can always get a little better each day
Car is sitting until the weather gets nicer will report an update as soon as its all wrapped up currently 17F outside and that's just a bit cold for me to be out there working on the car lol
*UPDATE* finally got back to working on the car after doing s compression check and getting all zeros i decided to pull the heads and see what was going on and every intake valve is bent at this point i wish i would not have had help in the matter and just did it myself reading how to's so if anything hopfully this serves as a lesson dont alway trust that people know as much as they say they do, i will be taking them to the machine shop tomorrow if it costs too much to fix sadly i will just be putting on the stock heads
That sucks! Good luck with getting your car running again. I had 2 cams go bad in a '73 Nova I have before I went roller cam. I helped a buddy install a new cam in his C6 and it was a piece of cake compared to old school flat tappets.
Well here we go the motors goin back together my body felt up to the task so i got to it yesterday gonna finish it all up within the next day or 2 man i cant wait to fire this thing up
Also for anyone that has an issue putting the head bolts back in the home made thread chaser worked wonders i could not thread the bolts in by hand but after running this threw the holes they all went in my hand easily, put 3 cuts in it and done
That's what I always do is slot a used stock bolt, works great.
Did you find out why the valves got bent in the first place? If not it's gonna do it again.
Edit: I read back up and saw where you said the cam was installed wrong and had the dot to the 0 instead of dot to dot so that is likely what bent the valves.
Hopefully you have the the crank gear on the right keyway now, I saw you said you got it dot to dot now but didn't mention if you checked for sure that the gear was on the right keyway for 0 degree's of advance or retard
