hi i am new at this,but i have a mach z improved with all kinds of great stuff ,we build our own engines,porting etc,but has anyone ever used the hemi design cyl head from rk tech,,and if so how does it work..
I ordered one for my 1994 Mach-Z and it works great...they also modified the water jacket holes for better cooling...before you order one Corey will want to know all the modifications that have been done to your sled and what elevation you will be riding at...also what octane fuel you will be using...Fett Brothers also does up heads also...Hope this helps...Al.
Where I sled: I sled where I can find snow or water LOL!!!!!
I know someone that will cut your stock dome for ALOT less than they want for a Rktech head. Allit is is a Hemi cut and the deck cut for your elevation,compresion, and octane gas. they've just marketed there head like crazy when in reality many,many other motor builders have been doing the same thing for a long time.
Dogg - Not true on all engines. The Series 3 engines cant have the head re shaped that much as there is not enough material to do it. It will be so thin that the head will crack. The stock heads can be cut to accept aftermarket domes, but the cost is that of an aftermarket head.
Most engines come with a semi-hemispherical dome asyways.
Who is this person that you can have do it?
