305 deck height
 

what seams to be the best dech height for 305 flat top with .028 headgasket for stocker motor

Re: 305 deck height
 

depends on piston skirt design \ piston to wall \ how much rock up - down at TDC. generally you can get away with .035 total...

its speedpro pistons with .0025 piston to wall

Re: 305 deck height
 

that is probably a slipper skirt that is very flexable so it stays quiet for granny while she's driving to the store... but any way, never used any of those stock pistons in a stocker so I still think your safe with .035 total. problem with the 305's is the ones that make power and don't go into valve float, will RPM 7400+. If that piston grows and flexes more than a tru racing piston it may hit the head hard enough to close up the top ring land or break the piston skirt at the oil ring groove
