yes tom i did go overboard and it does run boggy on the bottom but is faster on the top. as far as taking away from the bottom of the exhaust it was more of surfacing it and not really taking away from it but i hear you and will keep that in mind next time.

rocca, why do you say that it will have a hard time making run time? you are right but what can i do next time to prevent that from happening?

i know that taking a little away (no where near as much as i did) from the top of the exhaust port will increase rpm's but what else can i do to increase rpm's


thank you for all your replies
