Ya tj did the tune whats the biggest cubes I should go with a single 76 then if the 402s too big

 

370 imo.

 

Ok what should I do as far as the heads go get aftermarket or leave them stock or get the stock ones p&p

 

And how big of a single do I need to buy for a 402

 

For the heads -- decide if this is a max effort or you just wanna go fast... I run TEA stage 3 317's on my TT.

I'd look at something in the 88 range (GT42-88, PT88, etc.) as a minimum if you are willing to juice it a bit to spool it up.
