A very rare early Gp4 16v Fiat Abarth head under dev at GCRE, started as a raw-unfinished head straight from the factory, owned by the well-known Mick Wood for his 124 CSA.

More later,

Fully finished ex ports at 120 grade with final coarse Scotchbrite finish - finished excepting that there will of course be some corrective work to do around throat after inserts go in. Next job guides and seats. Ex ports are nominally 24mm dia thru, same as valve throat diameter.

Skipped a few photo steps on this 1st build but finally got the new GC design HTD pulleys in for this engine so here is a snapshot of one of them nearly ready for test.
