Hi, I have a 90 GTA with the L98 engine. I just got back from the local machine shop after getting a quote on getting the heads redone with 2.02, 1.60 valves, studs, etc. The final price was quite rediculouse.

I have found a set of 416 heads with the following specs:

1.94, 1.5 valves
screw in studs
bronze guides
5 angle intake seats
3 angle exhaust
back cut intake valves
bowl increase for bigger valves and flow
chamber wall relieved for bigger valves and flow
head surfaced back to 58cc

I can get these heads for about half what it would cost to redo my 083 heads. I think the comp bump from these would also go well with my cam i'm just not sure how well these will flow.

Any thoughts would be appreciated.

Edit: If a moderator see's this could you move it to the tech/ general engine section? Thats probably a better area. Thanks.

 

Do you think these heads would have enough flow for my set up?

54mm t-body
LT1 intake
CC305 cam, 220, 230 lift
28lb injectors
1 5/8 headers and full 3" exhaust, no cats.
