The 190's are small,and I dont consider them worth buying for any engine. Guys will buy 210 cc heads and port them and then talk about how 220cc heads would have been too big,it makes me laugh. The engine should run at least as well at every rpm with the big heads as with the small heads. The reality is that to get good velocity you only need a small portion of the runner with a small cross section,and a small manifold will provide that small area. I will be running a Comp cam 280 H hydr cam for now until I upgrade to a Hyd roller.
Any suggestions are welcome.
If you put 230cc heads on your engine with a small manifold it would run like it had small heads. Maybe later you will want to step up and the bigger heads will be there at that time.
