What are the specs on those Pro=Maxx heads your'e using??
I have no clue...The engine builder checked out several different heads...had I think decided on one (sidewinder maybe?)and I had ask around about it also and found a few things he didn't like about them after talking with a couple racers. After a lengthy discussion with Pittsburghracer I called Todd at Marsh Performance about a set of heads. I forwarded Todd's contact info to the engine builder and those two decided what to use...Also ended up getting the rockers and shafts and maybe even push rods through Todd.
