What do do with my AFR heads
What do do with my AFR heads I have one of the very first set of 190's made for LT1 back in the day. CNC competition porting package, 2.05 and 1.625 valves.
I think I am going to take the top end apart next winter. Should I plan to sell these heads and upgrade to bigger ones? Or just send these heads to AI or some place for porting and match a good solid roller to them? How well can they be made to flow? Or is it not worth all the hassle?
Thanks for any opinoins

My goal is super light dedicated drag car, 10s n/a maybe faster.
I'm deciding when this current n20 experiment grenades, do I start collecting LS parts or LT parts for my NA build. I'm leaning towards LT just becuase, but the darkside is so tempting. So I am just weighing out my options currently researching so I can decide to swap or not.
Edit: my combo is 3000lbs me in it, TH400, 5500 rpm stall, 28" tire, spool.
Looking for a nice "reliable" NA low 10 seconds.
Don't want to start spinning past 7000 if I stay LT

By your goals I wouldn't spend anymore money those 190s.Sell them out right to offset cost of new castings.As far as your goals are concerned you can reach them easily with the LT.You just have to spec a combo that works well together.Search joelster on here his combo is running your goals with afr227s

Ok thanks for the advice. I will have some fun with this combo a bit more and decide what to do. Since I don't want to spin over 7000 I'm not sure I'll have enough RPM for big heads unless I bore and stroke and and ... $$$

so then he needs to think 400+ cubes lol... not to thread jack but what kinda internals and machining does it take to get an lt1 to 400+ cubes
I have a "fresh" forged splayed 4 bolt 350 with windage tray. Sure it was built in the 1990's but it has hardly any miles on it. I will run it with the AFR's until it breaks, just thinking ahead. I hate doing things 2-3 times so this time I want a plan 
LOL
Well I watched a show on TV and how easy it was to change an LS intake manifold ... I don't know what to do. I guess I need some track time first with the new auto combo and should just focus on getting it running
