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! Review: Great heads to wake up a SBC! - Nice heads! I blew a head gasket on my 67 Corvette and decided it was time to upgrade to aluminum heads. These heads are the same casting as AFR “As cast” for 1/3 the price. Of course, you have to add valves, springs, valve guide plates, and seals, but they are still a good buy if you do the assembling. They needed quite a bit of flashing clean up. Using cartridge sanding wheels, I was able to get them smoothed out for flow and very clean. I put new springs on and lapped the valves. Installed height was 1.70 just as stock. They were incredibly flat when the arrived! Less than .0015 across in every direction. I got long tube headers, too, as the original exhaust flanges were rotted away. OMG! The car picked up a ton of power! Just amazing. It is just mind boggling how much more power it has with these heads and headers. All the way through the RPM range. You really notice it above 3000 rpm, though. The cam comes alive around there, so these heads really breathe and let it develop so much power above 3K! I wanted to do an LS3 swap, but now, I can wait, as these heads and headers combined to make the Mighty Mouse motor put out big block power. ## Features - 【Fitment】Compatible with Chevy SBC 302, 327, 350, 383 and 400 small-block engines manufactured in 1986. - 【Specifications】Intake Valve Diameter: 2.020" | Exhaust Valve Diameter: 1.600" | Intake Port Volume: 200cc | Combustion Chamber Volume: 68cc | Intake Port: Square | Exhaust Port: Square | Spark Plug Angle : Straight | 23 Degree Intake & Exhaust Valve Angles | 3-Angle Valve Seat - 【High Quality】High grade aluminum, bronze valve guides, hardened seats, advance port design for greater air flow.
