Whats the Best way to upgrade a stk 2.0 ?, how to get more PWR with stk parts,.. Options

[flmont]

Iam trying to upgrade my 2.0 type 4 and the machine shop is a little leary,..of going with bigger valve's for fear of the seats falling out,..so If I keep stk heads,..what are my choices for going for more PWR,..I know larger PC's are planned,.. 96MM,..with larger cam,..using weber carbs,..( ICT 34's is what came off the engine,.) I don't need to use those carbs, if there are better options ,..like 40 or 44's,..can I keep original crank and rods,. I would like to if there still good,..just trying to punch it up as much as I can using close to stk or stk parts,..??? they talked about higher compression ratio's,..??? Thanks Frank

I have been told from here,..that any larger than 96 MM takes to much meat from the case,.to equal longevity,..I wouldn't mind 101's I guess,.what would your build spec's be for a street engine,.and to pass emmissions at least once,...??? Thanks Frank

Others may have better info but I always thought sticking with 96s and going to a longer stroke on the crank was a better option than something like 103s.
