So I have rebuilt the bottom end on my b21ft with just new bearings and rings and block cleaned and what not. so pretty much a good condition stock bottom end.
My top end is or will be and have parts for.
Volvo 531 penta head
porting
.005 shave on intake
.020 shave on exhaust
Heavy duty valve springs rated to around 7500rpm
New everything else
seal, retainers, guides
I am putting in SS valves
46mm Intake
38mm Exhaust
My question is
Should i have done more to the bottom end to run this head setup?
