Gentleman
I've come back after a long absence for the same line of questioning. I've been doing allot of digging on the subject.
I already have a set of trick flows with new Ferrea valves on a 302 in a '90 mustang that runs low 13's with stock cam 3.55 gears and those rotten bfg drag radials....

I plan to build a 393 or 408 stroker and put the twisted wedge heads on it, then sell the '90 in favor of a recently acquired '69 fastback.

MOST stroker kits ARE NOT TWISTED WEDGE COMPATIBLE.
Because of the location of the valves. I have emailed / talked to several kit suppliers, TMD (see ebay) does supply a kit with nodular crank, H beam rods, and probe forged full floater pistons for $1089 +s/h that seams to be the best deal out there. They claim that the pistons are twisted wedge compatible and yield approximately 11:1 with 62cc chambers, I believe the twisted wedge chambers are larger than that.

As always, I'd check the set up with clay including a headgasket of the thickness you plan to run, and the valve to rocker clearance recomended by the cam manufacturer to make sure everything has enough room at max lift / duration, especially if you plan to index the cam at all.

Also, according to several machinists I trust, if you are going to spend lots of time in the high rpm range as in road racing, then stock rods will not do. H beams rods with forged full floating pistons are the way to go.
For bracket drag racing / street use, stock rods with arp bolts and forged pistons with pressed pins are fine.

I agree with the previous comment, if I had it to do over again, I'd go with afr heads, with a big stroker 205s with a smaller street engine 185s.....

Either way, check twice!
