The V8 Owners Forum -

Hello,

After spent time of discussion and taken several advices I started to modify the valve guide boss of my second pair of Buick 300 heads :

I taken some pictures before and after (sorry the quality of pictures) :









At this I use some flap wheels for easy work that's why inlets port look like polished but they will be sandblasted at the end to help good fuel/air mixture.

I would LOVE to know how the max ported Buick 300 heads stack up against the new ones from Real Steel....

I don't know if flow bench figures for RS F-85 heads are already aviaible.

But something sure Buick 300 heads are without comparison in term of porting development compared to Rover heads.
