I have been trying to decide on this for a few weeks now and just cant make up my mind if it would be worth it. The reason im thinking about getting some 243 heads is that in a year or so im going to put a 427 or 454 lsx engine in my car. I have read that the ported 243 heads will work great with my stock setup now, but what im debating on is when i get my new engine will i be able to modify these heads further to like a stage 3 job to accommodate the larger bore? Like i said i know they will be better than my ported 853 castings but i dont what to buy these and when i get my new engine have to buy a different set. By the way i have an ls6 block, ls6 manifold, and if i get the heads i will have a total ls6 engine. Would this be worth more for resale purposes or just keep the ls1 heads and get the better heads with the new shortblock? THanks

IMO it's not worth it if ur going to put a 4xx ci in ur car soon unless u can buy the LS6 heads cheap and at least get ur money back when u sell ur old setup. With a 4xx ci engine I would be watching the L92 heads to see how they perform, they look good out of the box but keeping an eye on them for a yr or so I'm sure the aftermarket company will figure out what the best porting is for ur setup that u choose.
first off what are the flow #s on ur LS1 heads?

i say wait also.then get you a set of heads that will suport that big powerplant.you will be out alot of time and trouble and extra money also if you have a set of 243s worked over twice.by the time you get the stroker you may want an aftermarket casting that flows huge air to keep up with that many cubes.
