thanx man i only just got this post but had already purchassed a holy blue on the w/e cause every automotive place i went to told me holly blue was the only one in that range i needed so i got one i also have a malpassi r/r reg
so i installedthem and it seemed that it was over fueling and spluttering so i comp tested my engine piston 1,3,4 like 180psi and no.2 was 80 so decided to take my engine out and check/rebuild it wen i stripped it i noticed no marks in the piston barrel so i took the pistons out and on no.2 between the rings it was all cracked and bits missing so now my plans are a full rebuild im going to send my cam of to get reground new pistons new rings (possibly forged pistons depending on $$$) probbably double valve springs aswell also i might aswell get my sump modded to b larger and get it baffled
is there anything anyone can recomend to this build as i do not kno that much about ??

wen i get time i will have to start a project build on this engine.
