I agree.. the cost of rebuilding vs new your
better off with new.. I'm running W-2s which are
iron and weight more(about 40# per set) but they
can be made to flow well.. I have mine at about
312 cfm(might be 315 now)but they are about max now..
I have a set of W-5s but an having a issue with them
at the present time.. but I will get them right.. they
flow 319 at 600 lift.. both take off set rockers.. but
the alum W-5s are 40#lighter
