Problem runs good but when you get on it and you get around 3500 to 4000 it skips a touch not bad but i know im losing power
#2 i have a ticking in my rockers the intake side are fine but all the exaust rockers are lose with the small shims but to tight with no shim

any suggestions


ok now questions do i need to upgrade to #24 injectors and what about the fuel pump
also what should i set the fp at

i plan on getting it tuned but want to get it close before i go also any sugestions one things i need to know or do before i go
thanks for your help

thanks for the help i got new rockers that fixed that problem and re gaped the plugs to 54 instead of the 41 i had it at that took care of the skip

is it possible to need different length push rods for the exaust then for the intake side
