We've used Texas-Speed and had great results.

what bore size?what valve size?too big of valve will hurt flow if the valve is too close to the cylinder wall.

what motor is it going in... and stages in cnc portings... look at flow numbers and test bore sizes... some stage 3 only flow 15 more cfm... seen one vendor posting a stage 3 was like 318 cfm... on a 408 and stage 1 was 312 on a 346... and a price tag was 600 more... so look at the the posting... and decide whats worth it

keep in mind air velocity... you can cut the crap out to get flow, but if the air velocity is sacrificed, its not worth it...

a mild cnc job is all i would do.. just to clean up the runners, and the more importantly the the bowls

man, i really dont see either of the 2 being a bad choice.... they both make great products...
