look at wisco pistons they make a 369/402 piston shelf piston .i did look in to his not to long ago for a 402 build .at the time i do not think JE SRP did not have any thing .it could be cheaper to find small chamber heads less you have alot of $$ in them . the old trw /speed pro are limited if you use the close chamber O port head with the 396/402 piston with the trw/speed pro 375 hp pistons they will hit on the ex side of the chamber and will need some work on the pistons or chamber it is a good idle to check it any way you go open or closed piston
