I have just got me a pair of these (well Iwould be fcuked with one hey!)

whats the best piston to go with these?

Wiseco high compression?

or those supplied by manufacturer?

not as fancy as the spike but claimed 5hp?

right hurry up, come on

The high compression T/S head needs a piston that fits that combustion chamber, you can buy the HD version or wiseco The wiseco is about 275 .
