The heads I purchased are not drilled for any smog equipment they are dart 195 aluminium heads. The heads are going to be bolted onto a 347 strocker which is not 50 state. Will ditching the smog crap ie smog o matic pump, egr, and the tubing interfere with computer controller? I run a cat less pro chamber already I know the egr is on the tb but what good is it without the smog pump? I am getting into what I consider the next level of performance.
