I somewhat recenlty bought a 72 Duster with a mostly stock 440 aside from a cam and typical bolt ons... I decided I wanted to do a quick tear down and do a budget rebuild that would include a few parts that I recently aquired. I have a set of ProMaxx Heads (Sidewinders) which are at 84 cc's, Harland Sharp 1.60 Rollers, Comp XE284 cam and a ported Eddy RPM intake. My question is since I am trying to do this on a budget, what pistons are a good bang for the buck? I have been looking at the KB236 or KB237 (not sure if the 237 will work with my heads being sort of a closed chamber). I am trying to acheive 10.5 or slightly better compression. I know the Speed Pro 2355's are a good choice for not much more money, my only concern is valve clearance as it appears they do not have much of a valve pocket compaired to other pistions. This motor will never see NItrous and once I complete my stroker motor the 440 bottom end will be placed in my truck after I top it off with my 452 heads.

Thanks
