Is the RB street port template good for both primary and secondary porting? I almost asked in another thread posted today, but decided to start a new one.

This is what I was planning on for a S5 TII. But after reading 2Lucky2The7's thread on porting to big I want to be sure. Before it is to late.

 

According to RB yes. However it will leave you with a fairly large primary and care needs to be taken to not encroach on the water jacket. For comparison sake, the Mazdatrix templates are more conservative on the primary port having two seperate templates for primary and secondary.

 

Thanks. I think I may adjust my primary porting away from the template and more to the conservitive side. Not too much, though. Opinions are welcome.
