Rb20 Head On Rb30 Block In R32

[SAF30L]

Hi Guys

I have an R32 GTST RB20 and want to put a RB30DET Together for it, but I want to retain the RB20 head, for wiring and not having to buy another head

Will Forged Pistons from the RB25/30 Conversion kit fit with RB20 head or will pistons kiss Valves.

The cylinder head does not line up with the block as the bore of the 20 and 25/26/30 are different. use an r32 RB25DE head and plenum, has the same wiring as an rb20. but anyway the wiring for a 33 rb25 is pretty much the same
