W2 and W5 take same rockers.........Yes

I would not mess around with any intake but the INDY......all others would be inferior.



Would you go to W5's over W2's?

heck just go buy the indy headed motor Bigs has for sale.



I need the cubes...I have a brand new 408 W2 motor i just had line bored and installed a girdle on, and the W5 heads flow a little more than my W2 heads.
