Help With Heads!
 

Hey there, i need some help deciding on buying a set of heads over what i have now. I can get a set of 441s with a 3 angle valve job 1.94/1.50 screw in studs and guideplates for $200. I heard that these arent bad heads for what they are. Any help?? Would i notice a difference? Is it worth the swap?
My engine:
1980 350 stock bottom end.
882 heads
weaind stealth intake
edelbrock 1405 carb
lunati 442/465 lift cam
msd dist.
1/58 flowtech headers into flowmasters
Thanks any advice is appreciated.

They're slightly better than 882's, so no, not really worth the trouble.
If you can stand a compression increase, a set of 64cc Vortecs would be the ticket.
