Well the first question is it worth it to port the stock 853 castings? Time is not an issue, but I do want GOOD flowing heads, good valves, springs, etc, etc. If the stock heads are worth porting, does anyone know of a good shop in So. Cali? What should I expect to pay?

 

hit up richard @ http://www.proheads.com/

i'd wager almost 2k when said and done.

 

For 2k, it seems like I can buy new assembled heads?

 

forgot you have your own core; ~1700. if you want real power dont scrimp on heads.
