I have some questions on a current build.
Heres a quick run down
Probe 331 kit
stock block
Early twisted wedge heads
TFS stage 2 cam
RPM II fuel injection intake
Fox style 75mm tb w/ egr delete
AFM power pipe
Pro-M 80mm MAS
Motor should be around 10.2-10.5 com ratio
N/A build maybe a little spary
My question is the roller rockers. I looked at a set of Crane Energizer 1.6 ratio rocker and he said they dont work my heads. He said they need to be trick flow rockers. He showed me the push rods he used and the top (maybe a 1/16 down) you could see where they had been hitting the rockers. I have looked a lot of set ups and it seems that almost any rockers can be used. I am thinking that he may of had the wrong length push rod.
So what roller rockers do you guys think I should use?

Also the heads have the o-ring machined around the com chamber.
What part # head gasket do I need?

Last of all, What kind of power and torque can I expect from this combo
thanks

I assume your running the 4-5cc flat top piston based on your static compression numbers. I would look for 360RWHP/380RWTQ+ depending on what chassis dyno you use.

I have run just about all the rocker brands, but for the price you can't beat the TFS pieces they are nice and work well. I also like the COMP Pro Magnums and Scorpions.

I would also agree that he most likely had another issue with a improper clearance.

The TFS gasket is 51400901 (a little cheaper, same exact gasket) or Fel-Pro 1006 LOC WIRE Head Gasket

I use comp pro magnums on myne, but about a year after i put my motor together i noticed that harland sharp made a set of rockers just for the TW head that are offset for the valve locations, you might wanna check them out.

But my comps work just fine for me so far, been about 20 passes and 3 to 5000 street miles
