Heads for my 85 Corvette 4+3 manual?

[jan-erik]

Hello I am new here.

I am going to buy new heads for my 85 Corvette. I am going to use the TPI Ported plenum large tube runners and bigmouth intake.

Some questions:

Do the assembled heads Iron Eagle or PRO1 have threaded holes for the stock accessories as sensors and AC and and....?

Do the heads have heatriser possibilities for the EGR system?

Do the angle plugs have difficulty to get clear of the TPIS longtube headers?

Can I use the stock non center valvecovers on the heads?.

I have a cam which have 221/230 @ .05 with .454 openening and 112 lobe separation. Is it possible to do an estimate of the hp possibility with these heads with the intake and exhaust described here??

And last are the prices pr pair?

Thanks and would very much appreciate some comments.

Hello Jan-erik,

The heads we sell are compatable with stock accessories, all the machined holes are there. In regards to the EGR port all of our I.E and Pro-1 heads do not have a heat cross over to use with ( EGR Style Manifolds ) the only head we have that incoperates the heat crossover is our SS head PN# 10024266A.

Your Long tube Headers should fit, but our plug location is moved closer to the center of the bore so a mock up of the stock headers will be required to say for sure.

All the std SBC heads we manufacture have both sets of bolt holes for your valve covers including perimeter style and center bolt locations.

Last but not least all of our pricing on line is individual. Please feel free to call our sales tech line any time between 8:30am and 6:00 pm Mon - Fri ET for retail pricing and availability.

Thanks,
