Default Re: GAZ intake valve

This is the situation I find myself in. Two weeks ago I sent my block off to Rich at Antique Engine Restoration for inserts. He informed me that the GAZ block weighed approximately 35 lbs more than a "B", but was uncertain where the water passages are and did not feel comfortable taking the intake to 1.7". Two weeks ago I was fine with that.
Yesterday I got my newly cast "B" head from Tod Buttermore and the compression ratio turns out to be 7:1, now i really would like to go to 1.7" intake.
