Quote: Thing is, by the time you buy some 906s, clean them; mag 'em; mill them; install new guides, valves, and seats; get a valve job; and enlarge the seats, you're halfway to a new set of aluminum heads.
true , but when you build to run in a class like FAST you HAVE to run stock iron heads , so the point of the cost is MOOT , you either bite the bullet and do it or buy the alum heads and bracket race .
i've got more money than the cost of ebroks in 2 sets of 906's i presently have , one because the shop i had dod them originally madethem flow worse than stock with their COMPETITION VALVE JOB , and i'm having another set done to be pure stock legal that will probably be as much as a set of ebrocks , probably more ...
