[QUOTE="Muskalade, post: 3975053, member: 33438"] For one you took this way out of perportion, im not going to tell you a hp number then have it not match, no ported heads say what hp they make, it varies too much on the application, for example my heads(same port work done) with cams and a stock eaton with a 2.8 pulley sould net around 520rwhp. But once again this will mean nothing since your probably not running the same things. As for the porting i do my own work, as for the heads nothing was enlarged just smoothed out which is what a stage one port is, when you start inlarging runners and bowls its a must to use a beanchflow or a cnc machine to do the porting to insure equal chambers. When runners are smoothed out and sanded to a near polished finish they flow better then the ruff surface that stock has. Probably in the next couple of weeks im going to get them flow tested to see the flow gain and also if they dont sell within the next couple of weeks im going to build up another motor with them Im not trying to be a dick but read up on cylinder head porting to understand the concept alittle better, since the first thing you ask is how much hp do they make which is the wrong question, i have a friend with a low hp cobra not more then 600hp running in the high 9s so dont believe hp numbers because thats all they are, numbers not times!
