manifold to head conversions and adaptabilities

There is a plethora of info on renix to H.O. swaps, i just spent an hour looking over it all and got a headache reading all the contradicting comments. I even tried “ “ within my search terms to narrow down the results to exact phrases.

For the peeps who have notched the dowels on the renix intake to move it up on the HO head, have you had leaks after you did this?
And for the drill and tap of the knock sensor, does any body have the size of the drill bit and tap I need to correctly do this once?


Thanks
