340 with edelbrock heads overheating

ok, i pulled the water pump off. Its a high flow one. I am going to replace it anyways. Dont like to reuse them anyways. I am thinking the colling system has a restriction. I stuck my finger into the holes for the coolant intake holes in to the block. One hole was severly restricted the other was not restricted. The restriction was silicon gasket maker i used when i put the timing cover on after the rebuild. This one side of the timing cover was quite pitted so i used alot of goop. I cleaned it out. But again i dont think i am going to get that lucky as the car was running with this restriction to begin with. i guess i will see.

not sure hoe smart this was but i used my shop vac and sucked the rest of the coolant out of the block with hopes of pulling anything else out that may be restricting. if this did not solve the problem off with the heads.

i dont think its the timing it just made no sence where even at 12 degrees of inital it would warm up within 5-6 minutes. i do like more inital and will try bumping it up to 18 and see what happens .
