I remember hearing about that the P8R head was the best head to put on a ls motor besides a vtec head. It supposedly flowed almost as good as a vtec head. Is this true? Ive heard it has bigger valves and exhaust ports i think. Am i able to run it on a b18b motor? My build im starting is going to be an 83mm ls block. I wanted to port my spare b18b head, but theres no point in doing it if the P8R head already flows better.

And i did try to search, but the server is down. Anybody have any facts about it?

some good info in this article. good luck!

 

Yeah i read through that. Some good info.

My question is can the P8R head which has 84mm combustion chambers fit on an 81mm or 83mm block?
