What numbers do you think I"d be lookin at?

Sorry, forgot to mention, need car to be streetable but do not care about manners.

 

That's perfection right there!

 

I'll give my standard answer for 113 headed cars:

Maximum of 280 RWHP

Add more for extensive porting, but if you can afford it, you can afford better heads too.
