hi all im thinking if i can find some cheap getting a set of alloy heads mainly for the weight savings and i think they should allready b ok for lpg is this right? what are the pros n cons against these vs 2v iron type? another reason is a trip to usa wich i should take advantage on for parts as here in uk EVERYTHING is rip off prices
also anyone tell me where i can get a impco 425? will this bolt upto a std holley bolt pattern
many thanx

Going from the title of your thread you were thinking about Edelbrock heads. Problem is Edelbrock don't make Cleveland heads. Look for CHI or AFD for alloy Cleveland heads.

The Impco 425 bolts onto a holley throttle/base plate.

It sounds like a bit of a waste to put decent alloy heads on a motor that can be fed by a single Impco 425(ie sub 350hp). Your iron heads can easily achieve that kind of power without much work.
