The more flatter or square intake shape is definitely going to make a stronger signal to pull fuel and air. The bridge is a bit narrow for reliability sake. Boost port up top, are yoou doing much to it? aiiming it, or enlarging the window on the sleeve side of things? Boyhesons, they need to be much larger if you wanna go through the trouble of adding them, they might as well actually flow. exhaust, just dont try and get to widee as you start getting way to close to the transfers very easily.

i like to keep the bottom corners of the exh as far away from the trasfers as possible (red arrows). i dont recomend you grind it any wider in that area. i cant recomend grinding the floor lower either

The durations are gona depend on base gasket thickness, if the cylinders have been decked, etc. Alot more tk it than just the distance from the deck.

thanks for the replies

 

i have a stock gasket base.

 

I will disarm and I'll put to make the booster, a 10mm drill meaby.

 

And the exhaust i'll to take 27.5 mm from the base cylinder.
