Ok so i just picked up a 7.0 shortblock with aftermarket crank and billet rods, needs new pistons shooting for 11.5 to one most likely as it will be a 91 octane street driven car. I dont have a set of matching heads so i was wondering how a set of cnc'ed lsa heads would do because i do have a set of those. And either a ported ls3 manifold or ported l92 whatever would be better. I realize ls7 heads are better but they are rather hard do find used and i refuse to pay for new ones. I'll be doing a custom patg cam and the car will have either a t56 or a 6060. BTW this will be in a 65 mustang

Thanks, Nick

 

LS7 heads probably flow less air than a set of CNC LSA heads. Who did the LSA heads?

 

They're not done yet. I was gonna do a boosted 6.0 with stock lsa's but came across the ls7. Probably would send them to wcch.


Anyone know of any used ls7 heads?
