Steam Holes ?
Does drilling steam hole in heads ruin them for other engines without steam holes? I have some Pro Iron Lightning heads and was looking at buiding a 400 SBC. If i drill the holes to run them can i ever use the heads again for a 350 or 383 or something without steam holes?

Thanks

No. Doesn't hurt a thing. In one of the little mini-motors, the head gasket covers up the hole.

no it doesnt.

the hole will leave a coolent mark on the head gasket, but it has no effect on the engines behavior...


ive swapped heads on and off my 400 a few times...
