BBC Heads 820 vs 292

HP HUNTER · 01-02-2017, 09:58 AM

If you flow tested 5 820 heads and 5 292/241 heads the 820 casting would have a better average. The 820 head also seems to respond better to modifications. The sort turn on the 820 exhaust is also raised more than the 292/241.

I can't remember, but the 820 always responds good when ported, the chamber is inefficient though.
