All the fast guys in Brazil use a damper.
I would not run an engine w/out one.
Some guys there even weld on there dampers as a standard practice.
Even w/a good damper you need to watch for vibrations.
Leelites,called my friends cylinder head shop trying to get info.
He (leelites) was trying to directly compare our 194-292 siamese SP ports cyl heads to a standard SBC port as far as flow numbers,but you cannot compare the two as they are vastly different.
From what my friend disscussed w/him,he really does not know that much about cylinder heads & my friend quickly shut him up,he was lost for words,which is hard to do, but I am/was proud my friend put him in his place(LOST) :-).
