Or you can gasket Match the heads to fit the manifold. I would be glad to help in either case.
Thanks for your help and fast responses.

Thanks for your help Casey. If you wouldn't mind PMing me and explaining how you would build up the runner with epoxy, it would be much appreciated! Thanks!

Casey Schnidar (developer of the port) and TSP dont for see step from the intake into the head being a problem. TSP already sadi that they are reworking the CNC program to lower the port and if he feels the need to send them his heads, they will run the NEW program on his heads.
With both of them being pretty positive that this wont cause a power loss or leave anything on the table, then i dont for see it being a problem. If it does become a problem, then that is a bridge we will cross in the future.
Thanks again Casey and TSP

It also appears that the Fast 90 manifold has been ported before for another set of heads and this would account for some of the intake port wall mismatch between the heads and the manifold.

I own a set of those's heads. I was told that I got the third set that came out off thier final program. I also confronted jason about the intake ports not matching up. I took his word for it and put them on and couldn't be happier. I ended up just port matching the sides and top of the intake (fast 90) when I decided to change my jetting my nitrous (because it's a direct port setup and a p.i.t.a to do on the car).

just wondering..
anyone? i really want to get these because they do not require flycutting with an MS3 which is sweet...thats with the bigger valves...BUT, i am concerned about this port issue...makes me want to just get some budget 5.3's or something...any news on this port issue?

I liked the idea of 62cc Heads and "smaller" intake runners. Made it easy to get plenty of dynamic and static compression without milling and/or flycutting. My cam selection was then no problem.
For my goals it worked. Plenty of TQ and crisp throttle response.
However, I totally understand from lilbuddy1587 original post his concerns.
Probably need more input from others who have tried this head along with various intakes etc. I'm sure others are running them.
lilbuddy1587, hope it works out for you. Erikthegoalie..took me over a year to decide on heads, so take your time.
Keep us updated..

Someone earlier said epoxy was a thing of the past, thats not so. Several serious engine builders still use epoxy to alter/repair ports ect. I would get with Fast before I used epoxy on there intake though. The epoxy has shown reliable on metalic sufaces but what about the plastic material. I would be concerned with it eventally sepperating from different expansion characteristics and being sucked into the backside of the valve or even into the cylendar.
