I am going to be getting SLP headers soon and I would like to get a set of the "dead soft" gaskets. Anyone have any good/bad experiences with a certain brand? I see Summit has Percy's and Earl's, should I just get the cheapest I can find? Also, anyone happen to know if Vortec heads are square or round ports? (or how to figure it out) Thanks!

 

I am currently using Flowtech aluminum gaskets with my SLP's.No leaks to date about 5,000 miles.I paid $40 at local parts store,didnt want to order a set and wait.I have used Percy gaskets on my collectors of my hedman headers I had on with my old motor with good results also.Either way I would say you will be ok.They all are about the same design and such,just price differences.I don't know squat about the Vortec heads ports,but I would guess square.I can tell you all about AFR's though,like that would help.
