Well I won’t say I’m never going to buy another set of Speedmaster heads

I shipped mine direct to PRH. I can't remember the details now however it was money well spent. He also did some minor bowl blending and though I am happy knowing that part of the engine is good to if I did it over again I would have spent money on Trickflows. But even then those would have went to PRH to get his seal of approval.... Aftermarket parts-that's just the way it is....
