does anyone here have trick flo heads for thier lt1? And if so did they cause a larger gap between the intake mainifold and the deck of the block?

 

first off, why are you looking at trickflows? and it shouldn't cause any issues no

 

other things that could make the gap seem larger,,, different thickness of head gaskets. heads that came off the motor have been plained for more compression or because they were warped or not flat. combination of the two.

 

num 1, whats the issue with the trick flo's. num 2 i think it was the head gaskets. My uncle had a blower with it and he never did the pistons just thicker gaskets for the compression. so its probly just that just wasent shur if maby the top of the heads were cut on a differnt angle causen the intake to sit higher. diffenetly dont want to have a blow out issue. lol

 

the reason i asked about trickflows is that most people will never have a need for an aftermarket head. most people's horsepower goals can be reached by porting the stock castings

 

i see what your sayin but they came with the motor mine as well use them. i just wasent shur if you were sayin that they were crapy heads lol.

 

trickflow makes a very quality head...but you said they were used with a blower, right? are you using a blower or going NA? if going NA, you may have issues with compression

 

i am going with n,a but like i said he dident use low compession pistons and i grabed thinner head gaskets i think i should b good with both of them things fine. is there somthin about the heads themselves on y you say that?

 

if i remember right, they're like 62cc and the stock heads are around 54cc which would cause a drop in compression

 

You should check the casting number on the heads and see what size the combustion chamber is. Anything over 54cc (as Whammer stated) is going to cause a drop in compression. If you were planning on running forced induction the bigger combustion chamber could be good, N/A is will cause losses.
