I chose these heads ....for the fact that. it's a 408..they out flow any Cathedral with a smaller test bore...and similar Runner size.....They have 12 degree valve lay out....... they match my LS3 intake........the port can grow for larger engine size(small thru large bore LS3 12 degree heads.... there may be enough material to port small runner to a large Runner size?..and Last ......Mast makes a good product....

Here's some technical info.... well not really...I was wondering about what happened to Mast Splayed valve ls3-7 head so I tried email and ended up talking to Horace he basically told me that is was a good head but at more Expense with rather questionable improvement it really wasn't any better than Standard 12* degree heads the cost would be in the 1499 range as the Intake & exhaust valve are splayed 3 degrees vs $1299.99 ea for standard Med bore heads...

I like the fact that it used standard intake and exhaust..while being a splayed head and 255cc's...I figure it was roughly 10 cfms better than LS3 med bore head and would have competed with Mast LS7 heads...1499 vs 1299 and a smaller port than the 274cc LS7 head...Why would they compete against themselves they could use this in future app.'s. I should have asked would they sell one of those left over splayed LS3 heads....
