Re: best heads for LT-1
Mine is a 398 LT1 I ran the AFR 210CC heads with a Edelbrock Lt4 Intake that was ported by Lingenfelter Performance untill now. I just got a set of AFR227's and I am freshening the engine and switching to shaft rockers and throwing a little more compression at it for next year. If you would like more info let me know I will try and type it all out. The car can go 9's in decent air with a good track with a Ed Wright tune up in the stock PCM.

Re: best heads for LT-1
I would avoid the Trick Flow heads myself. I have a friend with a 383" LT1 who has oil drain back issues. Full valve covers at the finish line are of no value. My old foot brake bracket engine ran mid/high nines @ mid 130s at 3200 lbs with ease. Still had the 4L60E trans. Pete Incaudo (was CNC Cylinder Heads) did the LT4 heads & intake. I would choose AFR if I was going aftermarket.
