I would think un shrouding the valve a win win. Those w5 heads we have need a big bore and stroke to work.
If you have the material why wouldn’t you?
I’m fairly conservative, and plenty of people have went much further, so I will error on the side of less.
It’s a caged street car, I want to live on 20-60 mile trips repeatedly and not get hot.
Maybe a half dozen trips to the drag strip a season.
The guy I’d like to wear out before he gets any more decrepit, has run a best of 10:17 usually runs around mid 10s doesn’t really drive it on the street though anymore. I will.
Gonna take something serious to get in the 10:00 range high 9s would be better.
