What is a reasonable maximum amount of boost a set of L92 heads could handle before lifting? Assume using an iron block and ARP studs.

General consensus ia around 750~ish WHP before durability is a concern.

I have heard theyll lift between 16 and 20. you may be making more than the shortblock will even handle at those numbers.

Go with a set that has thicker decks. Try a search, I'm pretty sure I remember reading a couple threads on this. Your better off going with AFR'S, ported 317's or 243's as the deck thickness is better. ARP studs help with a higher clamping force but avoid the heads all together.
