What is everyone's opinion on Port Flow Design? Early this year my cam gear slipped and bent some valves, so I got a complete Ferrea valve train from Port Flow and had in installed at a local machine shop. Last month I was getting low compression on one cylinder so I took the head off and one of the valves was leaking. Got it fixed at a different machine shop. Last night that same valve broke (about 1/10 of the valve is missing). I know have the engine out and I'm trying to decide whether I should send the head to Port Flow for their full headwork service, or take it back to the first machine shop that put the valve train in.

 

if it were me, and I had the funds available, I'd send it to portflow. you'll be hard pressed to find a bad word about them anywhere.

 

Did you send your head there John? What was the turn around time with them?

 

portflow ....turn around is 1 month with shipping it there and back

 

 

yeap, i sent it there

http://www.vapor-trail.net/head.html all my experience with them

 

Nice writeup John... like usual.

 

ah, if only i had more time...I'd be a writer and a dyno tuner

Well, it's decided. I'm sending the head off to Port Flow in the morning. Since this is going to take a month, I'd like to put another head on and get the engine back in the car. Would a b18a head work on this vtec block (b17a)? I've never had my b18a taken apart, so I don't know what the oil passages look like. Would it be as simple as using the LS head and LS headgasket?

 

They are the best, no doubt
