Rebuilding my moto

Dd50 block ported
Stock crank, 1500 center springs and yellow clutch springs, sef ramp, kelly pulley, runnin 6.5 and 7 weights, rrgs pipe, big teeth belt, corsa ported. Only runnin one metal gasket and a head gasket.

Any suggestions? Looking for top end. Should i put 2000 center springs?

Head gasket? I used the metal gasket on the bottom and green rubber ring for the head, basically stuff that came in the corsa kit. No need to use anything extra on the head with a stock crank. That'll lower ur compression.

Greetings:

The first thing I do after assembling a block is to measure compression. 140PSI can survive pump Premium fuel. Much more and you need higher octane.
The next thing to do is to perform a check of all the gasket seals with soapy water, looking for bubbles.
