360 heads on a 318, I know it has been beat to death...

I should get the heads milled .30, new valves (1.88/1.60 ), new springs, new guides and new seats.

Heres part of the problem in answering you. What comp. ratio are you at now. How far down the hole are the pistons? How many cc's are the 360 heads and what ratio are you looking for?

*** To be honest, I do not know the compression ration right now, the block I have was bought and bored .40 with new pistons. I don't have the paperwork on it. The pistons seem to be about 1/16 or so in the block at the highest point. They are Zollner pistons .40 over, and I have not been able to find any information on them.


Will I be able to use the stock pushrods? And will I need to have my intake milled at all?

Depends on the amount milled. Shorter Pushrods are not really expansive at all. Some poeple will shim up the rockers and shafts. I don't like that idea myself. I see it as a band aid fix.
When you mill the heads, you need to mill ethier the intake to head surface on the intake or the intake to head surface on the head. If you do the intake, then that intake is for that head only and you will have to mill the next intake you swap onto it so it will fit.

*** I would think that shorter pushrods are the way to go then. Just makes more sense to me.

and per your formula
To reduce the chamber volume, remove .0048" from the head surface per 1 cc of chamber volume.
For each .010 removed from the head, .0095" must be removed from the intake face of the head.

*** the heads I have are 66.0-72.5 cc and I am not sure what cc range I should be trying to get for best compression on a 318 with 360 heads?

Just questions that are coming to mind the more I read about this process. Sometimes, I think I should not read so much!

Mopers right. Read read read.
*** I am trying it is definately informative and so far has been quite a bit of fun.

I'll find the formula. It's in the MoPar engines book.


Thanks!!
