stock 87 tpi iroc, valve guides/seals are shot so i was thinking of getting new heads. this is a daily driver looking for some more power. im open for additional mods, not all out tho.

i wanna go with bottom end power on the heads, especialy considering its tpi. i lost bottom end power from the borla cat back install.
- is there any other recommendations/advice for the head section so everything works properly?
- am i gonna have to get bigger runners for the tpi setup?
- what parts need to be machined to match heads
- i saw a edelbrock head with egr valve, does this mean the smog system will still be functional?

before i fix the valve problem, i will be adding shorty headers, mac ypipe, 3 inch cat, new suspension/bushings. existing 3inch borla cat back

please post your thoughts, thanks
