#113 head question
does anybody know if the stock springs that come with the #113 aluminum vette heads can handle a zz4 cam's lift? i think it's a .510 on the exhaust side.

I don't know for a fact if they can or can't, but I would put in springs I know could regardless.
Almost without exception, factory production springs aren't up to the lift of a ZZ4 cam.
