Safe or a bad idea?

i have an 88 gt, converted to mass air. it has 103k miles, ive had it since 99k.

i have some edelbrock performer heads, and a e-cam to install. my compression is 135 in all cylinders, doesnt burn oil.

my plan is this winter or asap, just installing the heads. once i can afford a new shortblock i will install the cam with it also. does this seem safe or should i hold off all together until i can rebuild it also?

car will be seeing about 20 miles a day versus the 50 is see's now also if that matters. thanks for any input

ok. well i might just put my money on some afr's instead of edelbrocks now, and get a nicer intake/cam/shortblock later on.

main concern is putting heads on for the moment.

thanks for the input
