You can run it but it's not ideal and pretty big for a mostly street car. What did the heads flow at .612?

It's a little big but the 434 will swallow it nicely. I have a 421 with a 250/256 on 115lsa solid roller so you are in the same ballpark.

Yours is going to lope more than mine since the solid roller is a little smaller after lash is taken into account - mine will run like a 244/250. I'd go for it and then swap if you don't like it. It will make big power all through the powerband.
