318 heads

^^ what they said! ...simple, short, semi-smarta$$ answer - - clean up/refresh what you have and move on..
 
There's just too many variables

Daily driver/hot street machine/street strip ?
Gearing and stall how far your willing to go ?
Is this a rebuild or just bolt on ?

Basically stock heads can get you to 300hp
With a little port work can get you into the 1:1 hp per cid fully ported can get you over 400 hp.

If your looking for a relatively cheap heads the will flow decent and give a CR bump a set of EQ'S would work.
 
For all we know, "it's in a truck"

Is it a Poly? Magnum? LA? I know, it's a 318 BMW.....:rofl:
 
Is this going on an engine with stock pistons or upgraded pistons? Standard crank or stroker? The reason to ask is to see what general compression ratio is planned for the bottom end and to see if that is fixed or is still in the planning stages.
 
That old blue truck needs to be turned into a racecar hauler!
 
Well, with those pistons in a 4" 318 stroker, and undecked block, and 62 cc EQ heads, you're pushing over 11:1 static CR even with .051" thick gaskets. 65 cc Edelbocks are still at 10.7. So all of these heads options with those pistons and stroke are putting you up in a range of SCR that is abnormally high for the street and usually just for the strip with a pretty big cam... or with special fuels or skilled tuning only on the street. You need to get the combustion chamber size up in the low to mid 70's cc size to get the SCR down in the mid 9's range with piston and stroke. How hard do you want to push SCR and deal with making that work?
 
was looking at some speedmaster and pro comp on flea bay says 65cc. not sure yet just looking.
 
Just buy a kit that works with closed chambers.
 
There it is : The Seinfeld vagueness FABO thread: Nothing acheived anywhere,lol....
