Hi all,
I am going with the comp cam and in the meantime I am replacing my Performer intake by a Performer RPM Air-Gap intake (maybe not necessary to go Air-Gap but I feel like I should spend money to save the country
).
Thanks everyone, extra thanks to Kalli for his helpful graph. If you still have everything set up properly can you do the exact same (stock, comp, edelbrock) but with a non RPM intake? This way I will have all the info I need
-> dropping the car at the mechanic next Tuesday for 3-4 days of work.

you're welcome. I think the xe256 should be a good choice in your comination. max power @ 5500 and lotsa torque
from what I can see the performer head 1.9/1.6 (60329) have the same flow data as the rpm (60229) with 1.9/1.6 valves

if that's the case the graph doesn't need changing
can anyone confirm they're the same head just with change in emission?
Good look with your new mechanic. Hope he'll adjust your timing and carb with it and you should be flying

I was actually talking about my intake being Performer as opposed to Performer RPM (or even Performer RPM Air-Gap). I was just curious to see the difference it would make in the graph.

Hi,
I dropped the car at the mechanic this morning. He is going to:
- Replace my Performer intake by a Performer RPM Air-Gap
- Replace my stock cam by a xe256
- Fix my oil pressure gauge (constantly showing 0)
- Adjusting/tune everything so that I can get a smooth and driveable car (not the case since the new Performer heads)
I should be getting it back on Friday, cannot wait!

this gonna be a nice runner. want to hear as well :-)
glad the mechanic agreed to the XE256.
do make sure that you only use high Zinc/phosphour in your oil to not join the group of people who've eaten throuigh their camshaft and blame the manufacturer. it seems to be as little as 500 miles with the wrong oil and you're burned
