Why am I drawn to the aluminum??

Idaho,Edelbrocks,are corn cobs,out of the box.The extra hours ,to do a valve job ,and port add up.Like I posted earlier,30 to 40 hours personally porting a set of Edelbrocks. With their valve job,flowed 280,on the intake port. Hours spent porting- equals hourly rate.A good porting job alone,starts at 500 minimum .Worked at a head porting shop,for 3 or 4 years.Brian's RHS heads,are a steal.
