W-9's ported with a conservative approach and an eye towards mid lift flow #'s. I think they'll work O.K.
The whole motor is a series of compromises since it was built with stuff that was available and affordable over a couple - three year window.
It should have a bigger bore ( it's 4.125 " ), but that could change in the future. It could sure stand more cam ( 260 / 250 @ .050 and .668 lift ) , and it might like a bigger carb too.
But the time slip will be the final arbiter here.
This is the first time I have had a set of heads done up for me , but this is also the most motor I have ever attempted to screw together too......I didn't trust myself to home port them and had too much $$ on the table to risk messing them up.
I think I'll be happy with the end result.
If not , there is always a plan "B".
