Default Motor rebuild

So after an agonizing year of waiting I finally ordered all of the parts to rebuild my motor. The EJ20 short block, water pump, oil pump, and gaskets should arrive next week. Now however I wanted to know if there is anything I should do to my old heads in preparation of putting them onto the new block? I unfortunatly dont have enough money to send them out to get rebuilt. So if anyone has any tips that would be helpfull.

Thanks

Are they in dencent shape? You should at least clean them up and check them with a straight edge.

Or you could polish them. Before you put the whole motor together you should do some basic blueprinting.

Get the heads rebuilt. CHEAP in the long run.

But dont spend more than $250-300 if you can help it. And that includes EVERYTHING.

Leak test them first. If they do not leak then degrease and hot tank them. If they are leaking you can do a valve lapping or 3 angle job. Best place to go is your local machine shop.

I work in a machine shop. I would like to try and get away with not having to disassemble the heads. Are any of those suggestions something I can do with the heads assembled.

(sorry about all the newbie ?'s just want to do it right the first time.)

just check to make sure there not leaking, and then put them through a "jet wash" the hot tank chemicals is not good for the seals on the valves.

check them with vacuum
jetwash
put on car

done.

thats what i did with mine
