My take Do not do it; and I do believe they will fit, however those heads I’ve seen are not worth the time to install them. Time and time again I’ve seen those heads taken off before owner really rides it. Yes they are better than stock however they lack the needed port and polish work to really improve the performance you search for. Recommendation….. Look into sending your heads off to have port and polish work done to it. There you can keep your heads and have them done right the first time and they will install professionally cut valves and heavy duty springs and so forth. You should also go ahead and get some nice cams to set everything off….. Good luck
i bought a set of the se compressor heads and am happy with the results... they have the behive springs and will handle my 570 lift no problem... i lost 5 ponies on top but gained 8ft lbs tq @3k rpm... thought it was a good trade and only cost $600. new
