Gt40 heads are well worth the effort, along with 7/16s screw in studs, roller rockers and a girdle. With regards tot he short block, unless it's an ultra rare 271hp version, it will have 2 bolt mains, You can buy 4 bolt mains for it but you'll have to machine the block and line bore it, a good recommendation if you are going to track it.
 
Low 6000 RPMs to maybe 6500RPM may be doable without risk, but it may not help that pucker problem that may accompany that............even in the Boss, after 6000, I.m in unknown territory...for good reason, I suppose...............
 
an update???
well popped by the machine shop to see if anything has changed.. (hoping for a birthday present...lol)
the update was the cam was in and the motor is much less greasy and the heads/intake are ready to go... but the stroker rotating assembly delivery date is a very tentative late September as of today.. so maybe an anniversary present??. lol
this has been going on starts & stops since 1991 so 2 months is no biggie...
