Multiple engine questions
So i've been putting together a turbo build. So far i have the On3 Performance kit and the add on kit that had the injectors, maf...ect. I am using explorer gt40 heads and intake combo. I picked up a f-cam also. I am using the short block out of an 89 fox. Block is at the machine shop and it needs .030 over bore. So now here are my questions:
-I want to replace valve springs,retainers on the gt40's, what do you guys recommend (part numbers please)
-I was looking at these pistons kb116.03 KBS. Am i going to have any clearance issues with valves?
-What do you recommend for ring gap for 8-12 psi of boost
Sorry for the random questions but I've been searching for hours and feel like i've been chasing my tail. Thanks in advanced

1.I got the trickflow springs for the gt40s back when I ran them. If I was serious, I would look into a beehive spring.
2. no idea what piston that is after a copy and paste on google.
3. ring gap should be included in the box with the pisotns

http://www.jegs.com/i/Keith%20Black/...0002/-1?CT=999 is a jegs link to the pistons. Do you possibly know the part numbers for the Trickflows springs?
thanks

If you are interested, You could sell off your current GT-40 heads and buy the set that I just had fully rebuilt. They already have the springs on them. They were professionally done by a local racing machine shop. PM me if you are even partially interested. I'll show you the receipts!

How did you come to the conlusion that a dome piston and 10 pounds of boost is a good combo?

the FMS spring set that is recommended to be used with the letter cams will cost you about $220! The retainers are shaped differently on the exhaust valve to make up for the differences in factory installed height.
