Default 540s heads and cams

Looking to upgrade my 540s. What aluminum heads are you guys running? And what’s the biggest camshafts I can go with EMI Thunder exhaust? “Water reversion” I don’t have a problem putting headers on if the cam and header combo is a decent increase..

It has ported steel heads now and a Crane hydraulic roller cams...

Thanks!

Hard to beat 400+ cfm at 0.600” lift from a reasonably priced off the shelf head unported.
