ok- at the risk of gettin flamed and mamed if i buy brand new BARE heads what parts (in general NOT BRAND SPECIFIC)will be needed and what are some good questions to ask distributor-yes i am talking about 175cc china knock offs also what sort of machining should i expect -with out of the box aluminum ready to run heads between $1100.00-$1350.00 can $498.00 bare alum.new castings save enough to make a difference .the valves i want are manley pro flo they are $55. for 8 ,so that alone adds $110.00 -my target is $850.00 less rockers because the other name brand heads aren't shipped with rockers either.please leave politics out of this one and concetrate on CHEAPNESS-i am a CHEAP BASTARD as evidenced by the 68 CENT pilot BUSHING used so i could keep the same 4cyl T-5 !!LOL
