Crash test dummy Posted December 28, 2023 Share Posted December 28, 2023 C20XE ported, big valve head. GM casting – mid-term production (no mounts for the coil pack). +1mm waisted stainless inlet valves and +1.1mm waisted stainless exhaust valves. Bronze guides. Work completed by CTM Performance Heads. 42cc chambers with plenty of meat left on the head for a couple more skims if required in the future. Distributor mount has been removed so you would need a short exhaust cam for it. Most performance cams are short these days. I had this head done for my spare engine, it’s been assembled onto the block but hasn’t been run. No springs, caps or platforms are included. Bargain at £450 plus postage but collection would be preferred. 1 Link to comment Share on other sites More sharing options...
