RHS BBC HEADS
 

Can anybody tell me are the alum heads ok for nitrous ?

RHS BBC heads
 

This is not a direct answer, I know. But, I have used several sets of the PRO TOP LINE/ PRO ACTION/ RHS heads on BBC engines I have built without NOS. I have had no issues with them, they perform well and are a very nice, dense casting. The decks are fairly thick, the material is high quality, cast in New Zealand, in a up to date foundry. That said, why wouldn't they be good for nitrous?

i know the question was for bbc but edelbrock is starting to compete
with the foriegn casitngs by selling sbc aluminum heads for under
1k, around $900. bucks, its a start, the bbc head will probably be
next, good luck :wink:

Probably ok for a small shot (150/200) with good fuel and the proper safety precautions.

I wouldnt get carried away though, no fogging or anything like that.
