Well Pleased!
I purchased a set of these heads about 31/2 to 4 years ago,and put them on my almost new 383 stroker engine.I had a set of procomp aluminum heads on her and she was putting out 465hp at the flywheel and 435 lb ft of torque.I got in touch with Dan at Tri-star engine supply,(since this is where I purchased my engine) and purchased a set of these Proheader aluminum heads.I was very impressed with the quality of these heads,espically compaired to thr Procomp heads I had on my 1976 Stingray.After I installed them and got her on the dyno,she dynoed just over 500hp at the flywheel,and 465lb ft of torque.I was really amazed I at the increase in HP gained along with 435 lb ft of torque to 465 lb ft of torque.I have had them on my engine for 31/2 to 4 years and can not say anything bad at all about them,I am and have been really pleased with them and recommend them to anyone who wants to pick up serious horse power and torque in a weekend.
