Okay thank you very much for the info will do that. Well now to. Clean and wait to get the heads to the shop and then wait some more

Use a carbon scraper and acetone to clean the block surface and manifold. Do Not Knick The Metal. the shop will charge a small fee but they can hot tank your heads and blast clean you manifold for you. it will look purty.

okay so heres the thing i got my heads back intake back had a snag with the heater core entry line from he intake but its resolved now got the motor back together all good to go ready to run but the thing is it wont run. im sure i have it timed right almost positive. put the number one cylinder top dead center on compression stroke. point dizzy button at the no. 1 plug wire then tighten down and it should bust off running correct? am i missing something here i put the gas on the floor and it kinda sounds like its gonna start it just kinda speeds up with a loud banging noise not metel to metel loke a pop or ****. then thats all it will do pease i need some help

if your are backfiring then something is still off. i would recheck you initial engine an ignition timing again. perhaps you were not on the compression stroke as you thought.

These things have to be DEAD NUTS ON, not close ... either your timing is off or you improperly adjusted the rockers and some are stuck open or effecting the timing by being too tight or too loose.
