Loss of Power

[JP1979]

Hi all, I have a 325 1987 cabby and engine was running pretty good but I have had in apart being respected for almost a year... Before I restarted I replaced the hot leads and plugs and have now driven it home but have a massive loss of power.. It has no gutts at all and feels like a big loss of compression? Any ideas where to start or what I should be testing for... Slightly worried cylinder head or gasket but like yo check other possibilities first... Any help would've real welcome please... Thanks Justin
