Anyone tried this or maybe know does it fit?

I ask this because i have incomplete bpt engine in my garage (ignition distributor missing and a few less important things) so if its possible i would fitt N/A cylinder head from this 1.8 which is in my car on BPT block (hard to find ignition distributor for BPT here in Croatia, i would say mission impossible)

And if somebody know are the valve dimensions same on BPT and in 1.8 N/A (in that case would replace mine with sodium filled)

U can defo fit a BG NA head, and im fairly sure ive seen a BA head on a BPT block. The ignition is different on the BG to the BA, but with soem research u might find a soloution.
