I have a 86 mustang 5.0 and I have the motor tore down to replace the pistons and get a 30 over bore ,When I put it back together I am going to put a comp cam in and gt 40 heads with my for now stock intake ,but my question is can I use the stock roller lifters and push rods and also the samerockers or do I need to replace them.....

what is the lift on the cam and more than likely you will need hrder springs for the after market cam . on mine i changed my roller rockers but used stock replacement lifters so i can keep good idle and comp cams rods to be safe they are a bit stronger than stock .
were the heads on your 86 the e6 heads ? if so you might want to fly cut the pistons to insure clearence to the valves .

I am replacing the pistons and getting the bore since Im in there because I dont want valve clearance porblems with the stock flat tops the cam is a comp xe264hr with 512 lift and 114 lobe ...will that be a good on and what spring should I get

yes that cam will work, get comps recomended springs, and have the machine shop that instals them (theyll need to be cut for dual springs anyway, if you get comps) shim them acordingly so you have around 315 at .500 lift...

go with 7degree locks/retainers aswell.

everything else yo have will be fine
