6.0 Bore Block....When will the heads lift on NOS?
I did a search but did not find the info on this I was looking for. Plenty of threads on boost. I was bench racing with a friend and we were discussing a certain combo for drag racing. It would need to be under 365ci for a weight break so pretty much 6.0 block and stock stroke. Jet limit would be 38 on a fogger so roughly 375 shot depending on your tune-ups. It seems the block with a good crank and rods would live but what about the 4 bolt head set-up? the build would dictate a good set of heads so that would be where the money was spent. Would the 4 bolt heads live at this level? head studs and MLS or copper gaskets. goal would be bottom 8's quarter mile or bottom 5's n the eighth at 2700 lbs.
Anybody have any real world experience with NOS use on stock block/aftermarket heads? I know there is always an endless amount of opinions.

My old 408 went 5.30's @ 3250# with a small jet plate system. Heads, Cam and Pistons... get those three right and youll be in good shape at 2700. Youll want an aftermarket casting head, Im partial to Mast stuff, thick decks and good ports.
Nothing exotic is needed to keep the heads sealed, ARP studs, and cometics.

How bottom 5's are you talking?.... 5.20's or 5.0's? at those times it is a fair amount of power to shave 2 tenths.

wow, some interesting replies. thanks a lot for sharing your info. seems like a stock 6.0 block, Eagle/Callies rotating assembly, forged pistons would be plenty reliable on the short block. ARP studs and cometic gaskets would seal the deal.
of course the magic would happen up top. would there be a factory head (either stock or CNC'd by one of the sponsors) that would have a thick enough deck and flow possibilities? would a rectangle port head be better?
I find the thought of this combo interesting as i have been running sbc combos for a long time and have been learning the LS platform a little at a time while building a 5.3 s10 Blazer for street use. I do have a spare 5.3 and 6.0 block that would be a good foundation for a build to go in my foxbody roller
