the guy/shop that just did my 418 with eddie heads. He showed me how shrouded the valve is even at 4.08 bore.
Said there was 20 horse in fixing it.
He is VERY smart.. won enginemasters competition with a small block Mopar.. I will take his word for it being an issue.. and a 318 has a much smaller bore
