has been told by the guy told me there are a pair down here being sold but these ones are with the regular valve sizes, not like the new ones with bigger valves
Is this true ?
I have know the only real big diff is the thickness of the walls accepting more aggresive porting job, but from cast they flow about the same than 906 heads ( so then, practically the same than 452s ).
I'm not thinking on a more than templates porting job on my 452s... so... I AM WINNING SOMETHING on these ? If I get these Stage V heads is to NOT MAKE a porting job because they would flow more than my stock 452s.
To make a porting job with TEMPLATES( no more than that ), I preffer not spend more money.
I am doing wrong ? or do I need a slap because I wouldn't get the stage V heads ?
