The vast majority of our customers and members of our forum run European engines (we are based in the UK and not the USA), so we have very little experience of US V8 engines. We don't have heads with different chamber angles over here, so we have even less knowledge on that particular aspect of US motors.

All I can tell you in 'general' terms is the following;

1) If you want to add the max amount of nitrous to a motor while retaining the max level of reliability, you need the following;
i) Lower rather than higher compression
ii) The distance from the piston crown to the crown for approx 1/4 of an inch from the periphery of the piston inwards, should be as close to the same all the way round the perimeter.
2) The cam wants to be as big as possible on inlet and exhaust but the exhaust side should be considered more than the inlet.

If you contact this guy on Facebook, he's the most knowledgeable American on nitrous oxide and US motors that I've ever met, so he'd be the best guy to speak to.

thanks trev ,what is the name of the guy to contact on facebook

His name is Ron Clark. He's a bit of an eccentric and most other American nitrous 'experts' (lol) claim he's wrong about his think on nitrous (just as they claim about me, despite proving them wrong time and time again, as well as creating the most advanced nitrous products in the world) but I can assure you that he's MUCH smarter than all the others put together and his thoughts on nitrous are correct.

thanks mate .i found him thanks cheers for your help

My pleasure and if you get advice that contradicts what he says from ANYONE ELSE, ignore them.
