Review: Great set of heads. NO problems to report. - Out of the box, I was throughly impressed. Packed very well, no damage. Using a Machinist's Straight Edge, I checked the deck surface; spot on. All guides feel fantastic with the valves I purchased seperately. I lapped every valve to check the seats; once again......spot on. Ran a tap through every threaded hole; no issues. Very little casting flash inside the runners. Not required by any means but I spend some quality time with a Christmas tree burr and cartridge rolls just below the seat into the runners (smooth the transition) and smoothed the aforementioned casting flash. These heads show a ton of potential. I can't wait to get them on my SBC build!
