When I do eventually get new heads, how will I know which chamber size to go with. whats the advantages of going smaller or bigger or does it just depend on application. According to my sig which should i be going with. By the way car is street/strip daily driver so I will be going with 225's most likely either patriot or dart. No I will not be spending the extra for ARP, ETs.. etc.

 

Are you talking about combustion chamber size, or port volume?

 

combustion chamber size liek 59cc, 64cc, 68cc etc. dontknow which one i should do...

 

Call up a few sponsors and ask them what a good combustion chamber size would be for a 408. If your gonna start w/ a Dart head, the chamber size will mostly depend on how much you want to mill. And that will depend on how much PTV clearance you'll possibly have or whether or not ur willing to flycut.

 

is milling a neccessity with dart heads? whats an average price for it to get done?

 

Call up Dart, tell them your goals, and I'm sure they'll help you with that.

 

sounds good thanks man
