1965 impala 327 starting issues.

ok i recently pulled a perfectly running 65 327 out of my impala to replace head gaskets and seal a few minor leaks. i put it all back togather, and found TDC on the compression stroke, installed the distributor correctly, and added new accell plugs and wires. when i went to crank it over all it does is pop every once in a while, shoot a flame or two out the headers and even shot a flame out the carburator. i tried swiching TDC incase i had it on the exhaust stroke and everything but does the same thing every time. its driving me crazy because i cant figure out what could be wrong. can somebody give me some help or advice, thanks.

First off, check the firing order. 1 8 4 3 6 5 7 2. Make sure you don`t have any crossed, since 5 and 7 are right beside each other on the cap and on the engine it`s easy to cross them up. Next up it sounds like your off on the timing. Here`s how I do it. Remove the number 1 spark plug, pull the distributor cap. Bump the engine over until it almost reaches number 1, then pull the distributor. This is done so the oil pump drive rod is in the right place. Next, place your finger over the spark plug hole, have a assistant bump the engine over until you feel the compression blow your finger off the hole, when you feel it, bump it over until it reads 8 degrees before top dead center on the timing marks. Drop the distributor in pointing at number 1, it should drop all the way down since the oil pump drive rod is already in the right place. Put the cap back on and fire the engine off. Get your timing light out and finish up the timing specs. With the vacuum advance disconnected and plugged you`ll want 12 degrees before top dead center then reconnect the vac advance, make sure you connect it to a manifold or full time vacuum source (one that pulls vacuum full time, even at idle) then recheck the timing, it should be around 20 to 24 degrees. Test drive. Lastly, I wouldn`t run anything with accel written on it, accel is ultra cheap junk with a high price tag. There HEI caps melt, I`ve had many of the HEI supercoils be bad right out of the box, plug wires with really high resistance out of the box, 3 out of 8 bad injectors that were new, and countless others on this board can tell you the same thing.
