I picked these up last night. The work put into these heads are incredible. Just wanting some opinions on what their best for. Im getting my l76 freshened up to a 370. Think they will work ok? Heres some pictures.

 

wow those are sexy as hell im puttin a set on my Lq4 they should work very nicely on a high compression build

 

What 2.5 heads are those?

 

Their the 5.3 2.5s

 

What kind of compression are you looking at when you install them on your lq4? and any idea what size the dish is on a lq4 piston?

 

I belive the dish on an lq4 is about .007 deep ! I just know this or think i due kuz i worried of all that when i put i lq4 in and was up and down on pt.net searching for answers!

 

Thanks. I kind of want to keep it close to lq4 specs so I can unbolt these heads one day and go F.I. with the same short block.

 

i love love love my PRC stg 2.5 5.3 heads!!!

 

What hp/tq numbers do you put down with the ls1?
