I run Vito's Hemi Head 2. DONT BUY IT if you ever plan to do a 4mill stroker with stroker cut domes and do not have access to a lathe. For some reason, they cut the neck of their domes (O/D where the spark plug threads in) down to 1.002-1.000.
Pro Design, Noss Machine hell everyone runs like 1.008-1.010. Everytime I buy domes I have to modify them....Vito's doesn't make/sell stroker cut domes.
I also noticed that when whomever milled this particular head flipped it over for the 2nd op, they didnt get it aligned to the machine PERFECTLY so there is a little step in the through hole where the aboved mention dome slides in.
Vito's does, however, cut an oring groove in the neck so when you put the dome in the head, it stays put. No need for a spark plug, but then again everytime I have to buy an oring set its $19 and then another $12 something for shipping. BS!
