no idea what you are asking as these tend to be drilled at the factory i have heard of people adding a third hole in an IDA to make it more derivable.

sorry no idea i just used them as they were. after jets/tubes etc were sorted on the rollers. we never modded the progression holes as that, it seems, to be a road thing the VWs did.

agree with dusky on 13 as the one to look for , but have seen 152? ( 4 progressions) working well also, as well as a range of Weber clones ( FaJ,) .. these though are full race ie idle over 1500 and couldn't care less about performance under 4000 rpm.
