Hello first time post long time lurker. Im swaping over my heads in my truck do to the castech head issue GM had in my 05 silverado. I got a set of 862 heads to bolt on to my motor. everything is going well however i got one question for the guru's. my new reman heads have a deeper front and rear centre bolt pocket for the first bolt design (2 different legths of 11mm bolts) I ordered the bolts according to my trucks year all the same length. they went in fine and I torqued them up already. should I take them out and get new shorter bolts for those holes? will this effect anything? thanks for the help.

 

Anyone?

 

I did a quick search, difference is in the blocks not the heads. So you should have the correct bolts.
