About the MS230
Why make a new high performance head when there already are so many to choose from?
We have tried to take the best qualities from different heads and make one head with those qualities and even improved them.
No. 1 Cooling is very important in a high output, street driven type 1 engine. The MS 230 head has nine machined fins which means 50% more cooling area than the Super Flo and Comp Eliminator heads and 15% more than the 044 head.
No 2 Port shape and size are very efficient ie. the intake port flows 240 cfm @16 mm (0,629") 25" H2O straight from the casting without porting. The exhaust port flows at the same lift and depression 180 cfm. The SF,CE style intake manifold fits straight on. Tests are made on a SF 600 flow bench.
No 3 We have made a new rocker arm shaft with five studs instead of two as the original has. This shaft will give you the possibility to run more lift, spring and rpm which is the same as more power with reliability.
The two main rocker studs are still in the same position which means that the original style rocker arms like Pauter,GB,CB etc will still fit.
The head is primarily designed for street use but can of course be used for all out drag racing too.
Boresize 94.0 mm
Valvesize 48*37,5 mm
Power numbers and price will follow.

They also have a brand new state of the art roller throttle body!


Love finding people developing new things and having new ideas!!!
