Engine Build Ideas...PLEASE HELP.

I understand what u[moper] are saying.
But I don't think we are talking about 9k and 550hp.
When you go roller every thing goes up $ wise 'springs' pushrods for 240lbs-460lbs spring pressures.
Believe that it costs more than '$300' & '$400' & $90
Add springs, push rods,+tax/ship=$1000 long Valves + machining in some
cases.IMO
I would like to chat more but I gotta go.
