milled and 5 angle on 241's
 

iam debating weather i should do a new valve job with new valves and a 5 angle valve job with the head milled

i was wondering how much should i get the heads milled/ is it worth it

and is it worth it to do the 5 angle?


if so how much HP gains could i see from just that? a buddy of mine told me possible 30 to 40
